10. What is SOC?

11. What is SOC? The core function of a SOC (Security Operations Center) is to investigate, monitor, prevent, and respond to threats in the cyber realm 24/7 or around the clock. Per McAfee's definition of a SOC, " Security operations teams are charged with monitoring and protecting many assets, such as intellectual property, personnel data, business systems, and brand integrity. As the implementation component of an organisation's overall cyber security framework, security operations teams act as the central point of collaboration in coordinated efforts to monitor, assess, and defend against cyberattacks".

12. Preparation and Prevention The number of people working in the SOC can vary depending on the organisation's size . As a Junior Security Analyst, you should stay informed of the current cyber security threats (Twitter and Feedly can be great resources to keep up with the news related to Cybersecurity). It's crucial to detect and hunt threats, work on a security roadmap to protect the organisation, and be ready for the worst-case scenario . Prevention methods include gathering intelligence data on the latest threats, threat actors, and their TTPs (Tactics, Techniques, and Procedures). It also includes the maintenance procedures like updating the firewall signatures, patching the vulnerabilities in the existing systems, block-listing and safe-listing applications, email addresses, and IPs . To better understand the TTPs, you should look into one of the CISA's (Cybersecurity & Infrastructure Security Agency) alerts on APT40 (Chinese Advanced Persistent Threat). Refer to the following link for more information, https:// us-cert.cisa.gov/ncas/alerts/aa21-200a

13. Alert Severity Vs Service Level Agreement (SLA) Alert Severity Service Level Agreement (SLA) Low 24 hours Medium 12 hours High 1 hour Critical 15 minutes SLA Breach Impact Website / Server can be hacked. You broke the policy and agreement, hence your company needs to pay 4 Lakh rupees for each SLA breach. If you breach SLA more than 3 times, your company may terminate you. Your company is at very high risk of cyber-attack because of SLA breach

14. TTPs Within Cyber Threat Intelligence Tactics, techniques and procedures (TTPs) are the “patterns of activities or methods associated with a specific threat actor or group of threat actors.” Analysis of TTPs aids in counterintelligence and security operations by describing how threat actors perform attacks. TTPs describe how threat actors (the bad guys) orchestrate, execute and manage their operations attacks. (“Tactics” is also sometimes called “tools” in the acronym.) Specifically , TTPs are defined as the “patterns of activities or methods associated with a specific threat actor or group of threat actors,” according to the Definitive Guide to Cyber Threat Intelligence. TTP = https :// www.optiv.com/explore-optiv-insights/blog/tactics-techniques-and-procedures-ttps-within-cyber-threat-intelligence

15. Monitoring and Investigation A SOC team proactively uses SIEM (Security information and event management) and EDR (Endpoint Detection and Response) tools to monitor suspicious and malicious network activities. Imagine being a firefighter and having a multi-alarm fire - one-alarm fires, two-alarm fires, three-alarm fires; the categories classify the seriousness of the fire, which is a threat in our case. As a Security Analyst, you will learn how to prioritise the alerts based on their level: Low, Medium, High, and Critical. Of course, it is an easy guess that you will need to start from the highest level (Critical) and work towards the bottom - Low-level alert. Having properly configured security monitoring tools in place will give you the best chance to mitigate the threat. Junior Security Analysts play a crucial role in the investigation procedure. They perform triaging on the ongoing alerts by exploring and understanding how a certain attack works and preventing bad things from happening if they can. Reference – What is SIEM? - https ://www.trellix.com/security-awareness/operations/what-is-siem / What Is Endpoint Detection and Response? – https://www.trellix.com/security-awareness/endpoint/what-is-endpoint-detection-and-response /

16. Monitoring and Investigation During the investigation, it's important to raise the question "How? When, and why?". Security Analysts find the answers by drilling down on the data logs and alerts in combination with using open-source tools, which we will have a chance to explore later in this path. Response After the investigation, the SOC team coordinates and takes action on the compromised hosts, which involves isolating the hosts from the network, terminating the malicious processes, deleting files, and more.
