Persistence system protection
Our previous chapters focused on creating malware and carrying out different attacks. This is the offensive side of attacks. However, in real-life hacking, you need to know how to protect yourself against external attacks. A better understanding of protection mechanisms would help you to not only protect yourself, but this knowledge would also help you to carry out successful attacks. The first line of defense against external network attacks, or system attacks in general, is the Intrusion Detection System (IDS). IDS is an umbrella term for a lot of tools used for system security and protection, so we must learn about them in detail.
Intrusion detection systems
IDSes are a system that monitor and detect the components of your network or system on a continuous basis to detect any undesirable or suspicious behavior. The goal of an IDS is to prevent any undesirable scenario in a system. Fundamentally, there are three types of IDS:
- Host-based...
