Threat intelligence and threat hunting encompass the strategies used to detect and protect against active threats. Threat intelligence describes gathering and analyzing data to help identify potential threats and determine the most effective way to mitigate them. Threat intelligence enables the proactive identification of malicious activity and the capabilities and objectives of different threat actor groups. In addition, threat hunting describes actively searching for signs of malicious activity on an organization’s network. It involves using various tools and techniques to search for potential threats, such as analyzing log files, monitoring suspicious traffic, and performing manual searches. Combining these two approaches allows an organization to stay one step ahead of threat actors and better protect its systems.

Lesson 3: Explaining Important System and Network Architecture Concepts

System and network architecture are crucial elements to consider for security operations. Effective system and network architectures provide a secure environment for all software and devices and can resist attacks while maintaining authorized user access. Additionally, it should enable security analysts to detect and respond to malicious activity promptly. Lastly, it should be easy to maintain, allowing updates and patches to be applied quickly and seamlessly to all components. When appropriately designed, system and network architecture provide a secure and reliable environment for businesses and organizations, protecting them from threat actors and other threats.

Lesson 4: Understanding Process Improvement in Security Operations

The importance of leadership in security operations cannot be overstated. Leaders are responsible for setting the strategy, providing guidance and direction, and ensuring the safety of personnel and assets. They must be able to take decisive action and lead from the front in times of crisis. Good leaders will also be able to motivate and inspire their team, helping to ensure that everyone is working toward the same goal. Furthermore, leaders must understand the latest technology and trends to ensure that their team is equipped with the right skills and equipment. Finally, leaders must manage resources effectively, so operations are efficient, cost-effective, and secure. To accomplish this, security operations team leaders must depend on well-established processes. Processes define a standardized, preestablished method of completing various tasks. Processes ensure work is completed consistently, reliably, and error-free. Leadership is a critical factor in the success of any security operation, and good leaders are essential for the safety and protection of all personnel and assets.

Lesson 5: Implementing Vulnerability Scanning Methods

Vulnerability scanning is an essential component of network security. It identifies and assesses vulnerabilities that malicious attackers can exploit in a system or network. It is important to understand the different vulnerability scanning methods and the various concepts involved. There are two main types of vulnerability scanning methods: active and passive. Active scans require sending data to systems to check for vulnerabilities, while passive scans use existing monitoring tools such as IPS, IDS, and firewall logs to identify potential vulnerabilities. Understanding vulnerability scanning concepts is essential for effective vulnerability assessment and network security.

Lesson 6: Performing Vulnerability Analysis

Vulnerability analysis involves the evaluation of potential weaknesses in a system to identify and address any risks it exposes. Vulnerability analysis is a vital part of any cybersecurity program and is performed regularly to maintain a system’s security.

The process of performing a vulnerability analysis typically involves the identification of any potential weaknesses in a system, such as outdated software, unpatched applications, or misconfigurations. After identifying vulnerabilities, they are then evaluated to assess the level of risk they pose.

Lesson 7: Communicating Vulnerability Information

Communicating vulnerability information is a crucial element of cybersecurity. It is vital to ensure that the right people are aware of the information, the proper communication channels are used, and that the information is conveyed effectively. Reports, alerts, advisories, and bulletins are often used to provide vulnerability information.

To effectively communicate vulnerability information, it is essential first to identify who needs to be informed and the best way to inform them. IT staff, executives, managers, and other stakeholders, such as vendors and partners, must be aware of vulnerabilities and any related issues.

Vulnerability information must be presented clearly and concisely, including technical details such as identifying affected applications and systems and providing instructions on how to remediate the issue. It is also important to provide links to additional resources, such as patch advisories.

Lesson 8: Explaining Incident Response Activities

Incident response activities are the steps taken by organizations to assess, contain, and recover from cybersecurity incidents. These activities involve identifying and assessing the incident, implementing containment measures to stop the incident from spreading, and developing a recovery plan. Organizations reduce the risks associated with cybersecurity incidents by effectively identifying, assessing, containing, and recovering from incidents.

Lesson 9: Demonstrating Incident Response Communication

The goal of continuous improvement in incident response is to improve the overall quality and speed of response to incidents by gathering and analyzing data about past incidents, identifying areas for improvement, and implementing strategies to improve incident response capabilities. Continuous improvement involves deploying technologies and tools to automate processes and improve efficiency. In addition to deploying technologies, continuous improvement also requires establishing processes and procedures to ensure prompt and efficient incident response practices. It is essential to regularly evaluate incident response activities and implement feedback loops between the incident response team and stakeholders and use this feedback to refine processes and procedures. Finally, analytics measure the response teams’ performance and identify improvement areas.

Lesson 10: Applying Tools to Identify Malicious Activity

Identifying malicious computer activity is crucial to protecting a network from cyberattacks, unauthorized access, and breaches. Malicious activity takes many forms, from viruses and worms that can spread through a network to unauthorized access to a system and data. Rapid detection of malicious activity is essential to prevent widespread damage or a catastrophic data breach. Managing and inspecting log data plays a significant role in identifying malicious activity, and log data are also pivotal for forensic analysis. Network traffic and operating system monitoring are also key for detecting malicious activity as they provide real-time insight into the environment. By carefully analyzing networks, applications, and operating systems, it is possible to identify and respond to any signs of malicious activity quickly.

Lesson 11: Analyzing Potentially Malicious Activity

Analyzing potentially malicious activity is an integral part of keeping systems secure. When suspicious activity is detected, it is important to investigate it promptly to determine the appropriate incident response steps warranted to mitigate the threat.

Many methods can detect suspicious activity, but monitoring network traffic and examining operating system, user account, and file access activity is very common. Windows and Linux systems include many built-in tools designed to identify processes running on the operating system and the network connections associated with them. For closer analysis, several third-party software utilities exist to provide detailed insights into system and user activity, vulnerabilities, and potential configuration errors.

Lesson 12: Understanding Application Vulnerability Assessment

Application vulnerability assessment identifies, classifies, and remediates security vulnerabilities in applications. Identifying application vulnerabilities requires specialized tools for web applications, cloud platforms, or binary reverse engineering. Analysts can use these specialized tools to inspect applications and identify weaknesses that generalized scanning tools may miss. Most specialized assessment tools require a deep familiarity with the underlying application architecture and its programmatic operation to understand the identified issues; however, detailed report output provides the information teams need to work together and remediate vulnerabilities.

Lesson 13: Exploring Scripting Tools and Analysis Concepts

Malicious activity is any suspicious incident, including a precursor to an attack, unauthorized access, abnormal use, unusual utilization, a data breach, or denial of service, among others. It is important to be able to identify and analyze suspicious activity to protect systems and data from unauthorized access or unscheduled downtime. There are several ways to identify and analyze malicious activity, including monitoring system and network logs, analyzing use, endpoint protection software, and intrusion detection and prevention systems.

Lesson 14: Understanding Application Security and Attack Mitigation Best Practices

Application attack mitigation best practices involve protecting web applications and their underlying infrastructure from cyberattacks. Some examples of defensive measures include input validation, strong authentication, encryption, patching, security testing, and others. More than one protection method is required. Many approaches, spanning design through operation and maintenance, must be employed to help keep applications safe and secure.
