Hacking Linux and MacOS Damian Gordon

System Vulnerabilities Typical impacts are: Leaks of information Cracked passwords Corrupted databases Systems taken offline

Hacking Tools Rapid7 Nexpose Nmap https://www.rapid7.com/products/nexpose/ Port scanning, OS enumeration Nmap https://nmap.org/

Hacking Tools Kali Linux NetScanTools Pro https://www.kali.org/ Digital forensics and penetration testing NetScanTools Pro https://www.netscantools.com Port scanning, OS enumeration

Countermeasures Linux has a built-in firewall called iptables, and its successor nftables. Intrusion Prevention Systems (IPS) like PortSentry https://sourceforge.net/projects/portsentryctl/ Audit tools like SNARE(System iNtrusion Analysis and Reporting Environment) https://sourceforge.net/projects/snare/

File Sharing Linux uses NFS (Network File System) to share files across the network. This means it is vulnerable to attacks. If hackers can get access to this directory /etc/exports/ they can take full control of the system. You have to make sure it is safe.

File Sharing You should also monitor traffic using the firewall, port 111 is for NFS. Use both blacklists and whitelists to limit access to hosts. Make sure /etc/exports/ and /etc/hosts/ are configured properly.

Distribution Updates In Linux, different distributions have different tools: Distribution Tool Description Red Hat RPM Packet Manager Free and open-source package management system Up2date Downloads and installs new software and upgrades the operating system Debian Dpkg Used for installing, updating and deleting packages Slackware Pkgtool SUSE Yast2 A setup and configuration tool
