A Comprehensive Introduction to the 156-115.77 Exam and Check Point Architecture

The 156-115.77 Exam, officially known as the Check Point Certified Security Master R77, represented a pinnacle of achievement for network security professionals working with Check Point technologies. This certification was designed to validate an individual's deep understanding and ability to manage, troubleshoot, and optimize complex security deployments. It signified a level of expertise that went far beyond basic firewall administration, delving into the nuances of high availability, advanced VPN configurations, and performance tuning. While the R77 version is now considered a legacy certification, the core principles and technologies it covered remain fundamental to understanding modern Check Point environments. Successfully passing the 156-115.77 Exam required not just theoretical knowledge but also extensive hands-on experience. Candidates were expected to be proficient in designing and implementing security solutions for diverse and demanding network scenarios. The exam tested skills in areas such as intricate policy management, robust clustering for redundancy, and sophisticated threat prevention. Therefore, preparing for this exam involved a comprehensive study of the entire Check Point ecosystem, from its foundational architecture to the most advanced software blades. This series will explore the key domains covered in the 156-115.77 Exam, providing a deep dive into the concepts that defined a security master.

The Core Three-Tier Architecture

At the heart of any Check Point deployment, and a central topic for the 156-115.77 Exam, is the three-tier architecture. This model elegantly separates the management, enforcement, and user interface components, providing scalability, flexibility, and enhanced security. The first tier is the SmartConsole, which is the graphical user interface (GUI) client used by administrators to define security policies, manage objects, and monitor network activity. It is the primary tool for interacting with the entire security infrastructure, offering a centralized point of control for all security functions and devices across the network. The second tier is the Security Management Server (SMS). This component is the brain of the operation. It stores the network's security policy, the database of all network objects (such as gateways, servers, and users), and the logs collected from the enforcement points. When an administrator makes a change in SmartConsole, the change is sent to the SMS. The SMS then compiles this policy into a binary format that the enforcement points can understand. This centralized management approach is a key advantage, as it allows administrators to manage a global network of firewalls from a single location. The third and final tier consists of the Security Gateways. These are the enforcement points that are deployed at the network perimeter or internal segments. A Security Gateway receives the compiled security policy from the Security Management Server and actively inspects all traffic passing through it. Based on the rules defined in the policy, the gateway will decide whether to allow, drop, or encrypt the traffic. This separation of duties ensures that the resource-intensive task of traffic inspection is offloaded to dedicated hardware or virtual appliances, while the management functions are handled separately, preventing management tasks from impacting network performance.

Exploring the Security Management Server (SMS)

The Security Management Server is a critical component to master for the 156-115.77 Exam. Its primary function is to serve as the central repository and control point for the entire security policy. It hosts several key databases, including the object database, which contains definitions for every gateway, network, host, and user. It also houses the Rule Base, which is the collection of rules that constitutes the security policy. Administrators interact with these databases indirectly through the SmartConsole client, which provides a user-friendly interface for creating and modifying security objects and rules. Another crucial role of the SMS is policy compilation and installation. When an administrator is finished making changes to the security policy, they initiate a policy installation process. The SMS takes all the rules and objects, verifies their logical consistency, and then compiles them into an inspection policy. This compiled policy is then pushed out to the designated Security Gateways. This process ensures that all enforcement points have a consistent and up-to-date version of the security policy, which is vital for maintaining a secure and predictable network environment. The SMS also handles all administrative logging and auditing. Furthermore, the SMS is responsible for managing licenses for all Check Point products. Every Security Gateway and software blade requires a valid license to function, and the SMS acts as the central license manager. Administrators can attach and detach licenses from gateways through the management interface. The SMS also serves as the log server in many deployments, collecting and indexing logs sent from all the Security Gateways. This centralized logging is essential for monitoring, troubleshooting, and forensic analysis, allowing administrators to get a holistic view of security events across the entire network from a single location.

The Role of the Security Gateway (SGW)

The Security Gateway is the workhorse of the Check Point infrastructure and a key focus of the 156-115.77 Exam. It is the device that sits in the path of network traffic and actively enforces the security policy. Its sole purpose is to inspect packets and make decisions based on the rules it has received from the Security Management Server. This inspection can be as simple as checking the source and destination IP addresses and ports, or it can be a much deeper analysis involving application identification, user identity, and threat signature matching. The enforcement process begins when the SGW boots up and establishes a secure communication channel with its designated SMS. This channel, known as Secure Internal Communication (SIC), is based on SSL certificates and ensures that all communication between the management server and the gateway is encrypted and authenticated. Once SIC is established, the gateway can receive its policy. The policy dictates how the gateway's various security engines, known as software blades, should behave. These blades are modular components that provide different security functions, such as firewalling, intrusion prevention, or VPN termination. The gateway's performance is paramount, and technologies like SecureXL and CoreXL are designed to accelerate traffic inspection. SecureXL is a software-based acceleration layer that can offload certain traffic flows from the main inspection kernel, allowing them to be processed much faster. CoreXL allows the gateway to utilize multiple CPU cores for traffic inspection, significantly increasing throughput. A deep understanding of how to configure and troubleshoot these performance-enhancing features was a critical skill for any professional aiming to pass the 156-115.77 Exam and manage a high-performance security environment effectively.

Navigating the GaiA Operating System

The foundation of both the Security Management Server and the Security Gateway is the GaiA operating system. GaiA is a hardened, 64-bit OS developed by Check Point that combines the best features of their previous operating systems. A thorough understanding of GaiA is indispensable for anyone preparing for the 156-115.77 Exam. It provides a unified platform for all Check Point appliances, open servers, and virtualized gateways, simplifying management and administration. GaiA offers both a user-friendly web-based interface and a powerful command-line interface (CLI) for advanced configuration and troubleshooting. The GaiA web portal provides a graphical way to perform initial device setup and manage system-level configurations. Through the web interface, administrators can configure network interfaces, routing, system time, and user accounts. It provides a convenient way to manage the underlying operating system without needing to be a Linux expert. The portal is organized logically, allowing for easy navigation through tasks like backing up the system configuration, applying software patches, and monitoring hardware health. This interface is particularly useful for initial deployments and for administrators who prefer a graphical approach to system management. For advanced users and for tasks that require automation or deep-level troubleshooting, the GaiA CLI is the tool of choice. The CLI, known as clish, provides a structured command hierarchy that is more intuitive than a standard Linux shell. It offers features like tab completion and context-sensitive help to guide the administrator. Beyond clish, administrators can access the expert mode, which provides full root access to the underlying Linux shell. This is where advanced troubleshooting commands like fw monitor and tcpdump are executed. Proficiency in both the web portal and the CLI is essential for effectively managing and maintaining a Check Point environment.

Understanding Secure Internal Communication (SIC)

Secure Internal Communication, or SIC, is the fundamental process that enables Check Point components to trust each other. It is a critical concept for the 156-115.77 Exam because without a functional SIC, a Security Gateway cannot receive its policy from the Security Management Server. SIC creates a secure channel through which all communications between components are authenticated and encrypted. This ensures that a rogue device cannot impersonate a management server and push a malicious policy to a gateway, or that an attacker cannot eavesdrop on communications to steal sensitive information. The SIC process is initiated during the initial configuration of a Security Gateway. The administrator sets a one-time activation key on both the SMS object representing the gateway and on the gateway itself. When the gateway first contacts the SMS, it presents this activation key. If the key matches, the SMS and the gateway proceed to establish trust by generating and exchanging SSL certificates. These certificates are then used for all subsequent authentication. Once this initialization is complete, the activation key is no longer needed, and all future communication is secured using the established certificate-based trust. Troubleshooting SIC issues is a common task for a security administrator. Problems can arise if the activation key is typed incorrectly, if there are network connectivity issues preventing the components from communicating, or if the internal certificates expire or become corrupt. An administrator must be able to diagnose these issues by checking logs and using command-line utilities to test connectivity and reset the trust relationship if necessary. A solid grasp of how SIC works, how to establish it, and how to fix it when it breaks is a hallmark of an experienced Check Point professional and a key area of knowledge for the 156-115.77 Exam.

The Role and Function of SmartConsole

SmartConsole is the unified management client that administrators use to interact with the Security Management Server. For the 156-115.77 Exam, a deep familiarity with all aspects of SmartConsole was non-negotiable. It is a suite of tools combined into a single application that allows for the management of security policies, logs, events, and reports. The primary component within SmartConsole is SmartDashboard, where administrators create and manage the firewall Rule Base, define network objects, and configure VPNs. The interface is designed to be intuitive, allowing for drag-and-drop functionality and a clear visualization of the security policy. Within SmartConsole, the Logs & Monitor view provides powerful tools for analyzing network traffic and security events. Here, administrators can view logs in real-time as they are generated by the Security Gateways. The logging system is highly searchable and filterable, making it possible to quickly pinpoint specific events or troubleshoot connectivity issues. For example, an administrator can filter logs based on a specific source IP address, destination port, or rule number to understand why certain traffic is being blocked. This view also allows for the creation of customized reports to track security trends and demonstrate compliance. Another key aspect of SmartConsole is the management of Software Blades. Check Point's architecture is modular, and different security functions are enabled through these blades. Within SmartConsole, an administrator can enable and configure blades like Application Control & URL Filtering, Intrusion Prevention System (IPS), or Identity Awareness on specific gateways. The ability to manage all these diverse security functions from a single, unified console is a major strength of the Check Point platform. Mastery of SmartConsole means being able to navigate seamlessly between these different functions to build a cohesive and multi-layered security policy, a core competency tested in the 156-115.77 Exam.

Deep Dive into the Security Policy Rule Base

The Security Policy Rule Base is the core of any firewall configuration and a central subject of the 156-115.77 Exam. It is an ordered set of rules that the Security Gateway processes from top to bottom. When a packet arrives at the gateway, it is compared against the first rule. If it matches the criteria of that rule, the action specified in the rule is taken, and no further rules are processed for that connection. If it does not match, it is compared against the second rule, and so on. This top-down processing order is absolutely critical to understand, as an incorrectly placed rule can create security holes or block legitimate traffic. Each rule in the Rule Base is composed of several components. The source and destination fields define the traffic's origin and endpoint, which can be individual hosts, networks, or groups of objects. The service column specifies the protocol or port, such as HTTP for web traffic or SMTP for email. The action column determines what the gateway should do with matching traffic, with the most common actions being Accept, Drop, or Reject. Finally, the tracking column defines the logging options for the rule. A deep understanding of how to combine these elements to create precise and efficient rules is a key skill for any security administrator. A significant challenge in managing a large Rule Base is maintaining its clarity and efficiency. Over time, rules can become redundant or obsolete, leading to a bloated and confusing policy that is difficult to troubleshoot and can even impact gateway performance. Best practices, such as grouping related rules into sections, using descriptive names for objects and rules, and regularly auditing the policy for unused rules, are essential. The 156-115.77 Exam expected candidates to not only know how to create rules but also how to manage a policy for long-term scalability and maintainability.

Implicit vs. Explicit Rules

An important concept tested in the 156-115.77 Exam is the distinction between explicit and implicit rules. Explicit rules are the rules that are manually created by the administrator in the SmartConsole Rule Base. These are the numbered rules that define the specific security policy for the organization, such as allowing the marketing department to access the web or blocking access to specific malicious domains. Every rule an administrator adds, modifies, or deletes in the main policy view is an explicit rule. They form the visible and directly manageable part of the security policy. Implicit rules, on the other hand, are rules that are not directly visible in the main Rule Base but are automatically added to the end of the policy by the Security Gateway. These rules are configured in the global properties of the firewall and are designed to handle traffic that does not match any of the explicit rules. A key implicit rule is the Cleanup Rule, which is typically configured to drop all traffic that has not been explicitly allowed by a preceding rule. This "default deny" stance is a fundamental principle of network security, ensuring that only approved traffic can pass through the firewall. Other implicit rules may be added to allow specific types of control connections necessary for the firewall's operation. For example, implicit rules might be automatically created to allow management traffic between the gateway and the Security Management Server or to allow VPN negotiations. Understanding the complete order of processing, including where these implicit rules are enforced, is crucial for accurate troubleshooting. An administrator might see traffic being dropped and not find a corresponding rule in the explicit policy, only to realize later that it is being blocked by the implicit Cleanup Rule.

Leveraging Policy Layers and Inline Layers

As security policies grow in complexity, managing a single, monolithic Rule Base becomes challenging. The 156-115.77 Exam required proficiency in using policy layers to address this challenge. Policy layers allow an administrator to segment the Rule Base into smaller, more manageable sections. This is particularly useful in environments where different teams are responsible for different aspects of security. For instance, one team might manage the corporate firewall policy, while another manages the policy for the guest wireless network. Each team can be given permissions to manage their own layer, without being able to modify others. The main benefit of layers is improved organization and delegation of duties. Each layer has its own set of rules that are processed in order. The administrator can then define the order in which the layers themselves are evaluated. This creates a highly structured and modular security policy. When troubleshooting, an administrator can focus on a specific layer relevant to the issue, rather than having to search through thousands of rules in a single flat list. This approach significantly improves administrative efficiency and reduces the risk of misconfiguration. Inline layers offer even more granularity. An inline layer can be thought of as a sub-policy nested within a single rule in a parent layer. A parent rule might define a broad condition, such as "all traffic from the internal network to the internet." Instead of a simple "accept" action, this rule could be set to trigger an inline layer. This inline layer would then contain a more specific set of rules that apply only to the traffic matching the parent rule, such as rules for application control or URL filtering. This allows for the creation of a hierarchical and very detailed policy structure.

Mastering Network Address Translation (NAT)

Network Address Translation (NAT) is a fundamental networking technology and a critical topic for the 156-115.77 Exam. Its primary purpose is to modify the IP address information in packet headers while they are in transit. This is most commonly used to allow multiple devices on a private network, which use private IP addresses (like 192.168.1.0/24), to share a single public IP address to access the internet. This technique, known as Hide NAT, is essential for conserving the limited supply of public IPv4 addresses. In a Hide NAT configuration, when a device on the private network sends a packet to the internet, the Security Gateway replaces the private source IP address with its own public IP address. It also typically changes the source port number. The gateway then keeps a record of this translation in a state table. When the response comes back from the internet, the gateway uses the state table to translate the public destination IP address and port back to the original private IP address and port, and forwards the packet to the correct internal device. Another common type of NAT is Static NAT. Unlike Hide NAT, which maps many private addresses to one public address, Static NAT creates a one-to-one mapping between a private IP address and a public IP address. This is typically used to make an internal server, such as a web server or an email server, accessible from the internet. An administrator would configure a Static NAT rule that translates a specific public IP address to the private IP address of the internal server. This ensures that any traffic sent to that public IP address is automatically forwarded to the correct server on the internal network.

Implementing Application Control and URL Filtering

Modern network security, as tested in the 156-115.77 Exam, goes beyond simply looking at IP addresses and ports. The Application Control and URL Filtering software blades provide next-generation firewall capabilities by allowing administrators to create policies based on applications and web categories. The Application Control blade can identify thousands of different applications and protocols, regardless of the port they are using. This is crucial because many modern applications use techniques like port hopping to evade traditional firewalls. With Application Control, an administrator can create highly granular rules. For example, they could create a rule that allows employees to access Facebook for general browsing but blocks the use of Facebook chat or games. This level of control allows organizations to enforce acceptable use policies and prevent productivity loss without having to block entire websites. The blade uses a combination of signatures, protocol analysis, and behavioral patterns to accurately identify applications, providing a much deeper level of visibility and control over network traffic. The URL Filtering blade complements Application Control by allowing administrators to control access to websites based on their category. It uses a massive, cloud-based database that categorizes millions of websites into groups such as social networking, gambling, news, and malware. An administrator can then create rules to block or limit access to entire categories of websites. For example, a school might block access to all gambling and adult content websites. This is far more efficient than trying to manually maintain a list of every website to block, as the database is constantly updated automatically.

Effective Logging and Monitoring

A security policy is only as good as the ability to monitor its effectiveness, a key principle for the 156-115.77 Exam. The logging and monitoring capabilities within SmartConsole provide the necessary visibility into what is happening on the network. Every time a connection matches a rule that has logging enabled, the Security Gateway generates a log entry and sends it to the Security Management Server or a dedicated log server. These logs contain a wealth of information, including the source and destination IP addresses, the service used, the rule number that was matched, and the action that was taken. The Log Viewer in SmartConsole is a powerful tool for analyzing this data. Administrators can create custom queries and filters to quickly find the information they need. For instance, if a user reports they cannot access a specific application, the administrator can filter the logs for that user's IP address to see which rule is blocking their traffic. The ability to efficiently navigate and interpret logs is one of the most important day-to-day skills for a firewall administrator and is essential for rapid troubleshooting of connectivity problems. Beyond simple logs, the SmartEvent component provides advanced security event analysis and correlation. SmartEvent processes the raw logs and identifies significant security events and patterns. For example, it could correlate multiple failed login attempts from a single IP address and generate a single high-priority event for a potential brute-force attack. This helps to reduce "log fatigue" by bubbling up the most important events that require an administrator's attention, rather than forcing them to sift through millions of individual log entries. This level of intelligent monitoring is crucial for proactive threat detection.

Advanced Policy Configuration Options

The 156-115.77 Exam delved into many of the advanced options available within the security policy that allow for more granular and context-aware rules. One such feature is Time Objects. Time Objects allow administrators to create rules that are only active during specific times of the day or on specific days of the week. This is useful for implementing policies such as allowing employees to access social media sites only during their lunch break, or for performing scheduled maintenance that requires temporarily opening a specific port. Another powerful feature is the ability to create rules based on the direction of the connection. The Rule Base can be configured to distinguish between traffic originating from the internal network going out (outbound) and traffic originating from the internet coming in (inbound). This allows for the creation of different security postures for different traffic flows. For example, an organization might have a relatively permissive policy for outbound web browsing but a very restrictive policy for inbound connections, only allowing traffic to specific, well-secured servers. Furthermore, the concept of a Domain Object is important for rules that need to apply to a service that uses many different IP addresses, such as a large cloud provider or content delivery network. Instead of trying to maintain a list of all these IP addresses, an administrator can create a Domain Object based on the service's domain name. The Security Gateway will then dynamically resolve this domain name to its current IP addresses and apply the rule accordingly. This greatly simplifies policy management for services that have a dynamic and large IP address footprint.

Fundamentals of IPsec VPNs

Virtual Private Networks (VPNs) are a cornerstone of modern network security, and a deep understanding of their operation was mandatory for the 156-115.77 Exam. The most common type of VPN is an IPsec VPN, which provides a secure method of connecting two or more trusted networks over an untrusted network like the internet. IPsec is not a single protocol but rather a framework of protocols that work together to provide confidentiality, integrity, and authenticity for data packets. Confidentiality is achieved through encryption, ensuring that even if an attacker intercepts the data, they cannot read it. Integrity is provided through hashing algorithms. Before a packet is sent, a hash (a unique digital fingerprint) is calculated. This hash is sent along with the packet. The receiving end recalculates the hash and compares it to the one that was sent. If they match, it proves that the data was not altered in transit. Authenticity ensures that the two endpoints of the VPN tunnel are who they say they are. This is typically achieved using pre-shared keys (like a password) or digital certificates. The combination of these three services creates a secure and trusted communication channel. The IPsec framework operates in two modes: tunnel mode and transport mode. In tunnel mode, the entire original IP packet, including the header, is encrypted and then encapsulated within a new IP packet. This is the most common mode and is used for site-to-site VPNs, as it completely hides the internal network addressing scheme. In transport mode, only the payload of the original IP packet is encrypted; the original IP header remains intact. This mode is typically used in host-to-host communications where the path of the data is already considered secure.

The IKE Negotiation Process

Before an IPsec VPN tunnel can be established, the two endpoints, or peers, must negotiate a set of security parameters. This negotiation process is handled by the Internet Key Exchange (IKE) protocol. This process is a critical element to understand for the 156-115.77 Exam, as failures in this stage are a common source of VPN problems. The IKE negotiation happens in two distinct phases. IKE Phase 1 has the primary goal of establishing a secure, authenticated channel between the two VPN peers. This channel is itself a tunnel, often called the IKE Security Association (SA), and its purpose is to protect the negotiations that will happen in Phase 2. During Phase 1, the peers authenticate each other using either a pre-shared key or digital certificates. They also agree on the encryption and hashing algorithms they will use to protect the Phase 2 negotiations. They use a cryptographic technique called the Diffie-Hellman exchange to securely generate a shared secret key without ever sending the key itself across the wire. Once Phase 1 is complete, both sides have a secure channel and are confident they are talking to the correct peer. IKE Phase 2 then occurs over the secure channel created in Phase 1. The goal of Phase 2 is to negotiate the specific IPsec Security Associations that will be used to protect the actual user data. The peers agree on the IPsec protocol to use (either AH or ESP), the specific encryption and hashing algorithms for the user data, and how often the encryption keys should be refreshed. They also define which traffic should be sent through the VPN tunnel. This is known as the encryption domain. Once Phase 2 is complete, the VPN tunnel is up, and data can flow securely.

Configuring Site-to-Site VPNs

A site-to-site VPN is used to securely connect two entire networks, such as a company's main office and a branch office, over the internet. From the perspective of the users on these networks, it appears as if they are part of the same private network, even though their traffic is traversing the public internet. A core part of the 156-115.77 Exam curriculum involved mastering the configuration of these VPNs within the Check Point environment. The process typically involves creating network objects to represent the Security Gateways at each site and the internal networks behind them. The concept of a VPN Community is central to Check Point's implementation of site-to-site VPNs. A VPN Community is an object in SmartConsole that groups together multiple Security Gateways that need to form VPN tunnels with each other. Within the community object, the administrator defines the shared VPN properties, such as the IKE and IPsec encryption and authentication settings. This greatly simplifies configuration, especially in a hub-and-spoke or mesh topology. Instead of configuring peer-to-peer settings between every gateway, the administrator simply adds the gateways to the community, and the necessary tunnels are automatically created based on the community's settings. Another critical aspect of site-to-site VPN configuration is defining the encryption domain for each gateway. The encryption domain is the set of networks and hosts that are allowed to send and receive traffic through the VPN tunnel. If a host behind a gateway tries to send traffic to a destination that is in the remote gateway's encryption domain, the gateway will encrypt the traffic and send it through the tunnel. If the destination is not in the encryption domain, the traffic will typically be sent out to the internet unencrypted. Correctly defining the encryption domain is crucial for ensuring that sensitive traffic is protected.

Remote Access VPN Solutions

While site-to-site VPNs connect networks, remote access VPNs are designed to provide secure access to the corporate network for individual users, such as employees working from home or traveling. The 156-115.77 Exam required knowledge of the different remote access solutions offered by Check Point. These solutions involve a software client installed on the user's computer (such as a laptop or smartphone) that establishes a secure tunnel back to the corporate Security Gateway. This allows the remote user to securely access internal resources like file servers and applications as if they were physically in the office. One of the key challenges with remote access VPNs is authenticating users. Check Point supports a wide range of authentication methods, including simple usernames and passwords, RADIUS, SecurID, and certificate-based authentication. Integrating with an existing user directory, such as Microsoft Active Directory, is a common practice. This allows administrators to grant VPN access based on a user's group membership, simplifying user management and ensuring that only authorized employees can connect to the network. Check Point also offers different modes for remote access. Office Mode is a feature that assigns the remote user an IP address from the internal corporate network. This makes the user's computer appear as if it is directly connected to the office LAN, which can simplify access to certain network resources. Another option is Visitor Mode, also known as SSL VPN. This feature encapsulates the VPN traffic within a standard SSL/TLS tunnel (the same technology used by HTTPS websites). This is extremely useful when the user is behind a restrictive network, such as a hotel or airport Wi-Fi, that might block standard IPsec traffic.

VPN Troubleshooting Techniques

VPNs are powerful but can be complex to troubleshoot when they fail. A significant portion of the expertise required for the 156-115.77 Exam was in diagnosing and resolving VPN issues. Common problems include IKE Phase 1 or Phase 2 negotiation failures, issues with routing over the VPN, and mismatched encryption domains. A systematic approach to troubleshooting is essential. The first step is often to check the logs in SmartConsole, which can provide detailed information about why a tunnel is failing to establish. The logs will often indicate the specific point of failure. For example, a log message might indicate a "no proposal chosen" error, which means that the two VPN peers could not agree on a common set of encryption or authentication algorithms. This would prompt the administrator to check the VPN community settings on both sides to ensure they match perfectly. Another common issue is a failure in authentication, which could be caused by a mismatched pre-shared key or an issue with the digital certificates. For more complex issues, command-line tools are indispensable. The vpn debug utility on the Security Gateway provides a real-time stream of the IKE negotiation packets, allowing an administrator to see the exact proposals being exchanged between the peers. This level of detail is invaluable for diagnosing subtle configuration mismatches. Another powerful tool is fw monitor, which can be used to see if the traffic is being encrypted and decrypted correctly by the gateway. Mastering these troubleshooting tools is what separates a novice administrator from a security master.
