Even logs on Windows servers are often collected by Linux systems (including those running SIEM), where regular expressions can be used to narrow down key security-related events. Regular expressions are powerful wildcards used alongside certain Linux utilities to search system files and logs for key events on a wide variety of network devices and servers. Connect to remote systems using a wide variety of different methods, including ssh.Analyze the content of key or suspicious files.

View and work with the different physical and logical filesystems on the system (mount points, LVM, ZFS, btrfs, etc.), including imaging data on a filesystem for analysis and evidence gathering using utilities such as dd.

Regardless of whether you are performing penetration tests, forensic analysis or security monitoring of a Linux server, network device or security appliance, you will need to understand how to perform key system and network administration functions within Linux.

Linux System and Network Administration.

In this blog post, we’ll examine five key areas of Linux that cybersecurity professionals must master. In short, if you are planning on working as a cybersecurity professional, you’ll definitely need an excellent working knowledge of the Linux operating system. 5 Key Areas of Linux for Cybersecurity Professionals This is especially important today considering that most servers in the cloud run Linux, and that more and more companies are moving their data to the cloud. Of course, on-premises and cloud-based Linux servers that host services and data will also be a focus of any cybersecurity professional. Consequently, to collect security-related data from these devices or perform security hardening, you must first understand Linux. Moreover, Linux is the operating system used on most network devices and security appliances, including routers, firewalls, next-generation firewall (NGFW) devices, unified threat management (UTM) gateways, virtual private network (VPN) concentrators, intrusion detection systems (IDS), intrusion protection systems (IPS), security information and event management (SIEM) appliances, wireless access point (WAP) devices and more. Specialized Linux distributions such as Kali Linux are used by cybersecurity professionals to perform in-depth penetration testing and vulnerability assessments, as well as provide forensic analysis after a security breach. Linux plays an incredibly important part in the job of a cybersecurity professional.

Implementing technologies and processes to harden the security of systems and networks.

Investigating and performing post-mortem analysis of a security breach to identify the data accessed and the exploits used by the attacker.

Monitoring and reacting to security breaches to mitigate data loss.

Analyzing the security of systems and networks by performing penetration testing and vulnerability assessments.

Cybersecurity professionals perform a wide variety of different roles, including: The need for security to protect the data on systems and networks has skyrocketed in recent years.
