Keeping up with vulnerabilities and threats

Attacks on networks often result from the exploitation of existing vulnerabilities, therefore, is it important to fix and keep up with all existing vulnerabilities in the network to prevent threat exposure to the aforementioned threat vectors. This is exactly what we will be learning to do in this section.

Researchers explain that there are a lot of inherent loopholes that lead to network vulnerabilities. These gaps expose the infrastructure to a hacker to readily commit cybercrime. For example, missing data encryption is an opening that makes a network vulnerable and needs to be fixed. Some organizations have inadequate password policies; these passwords are simple and easy to guess and an intruder will not struggle to break into the database by cracking them if a change is not enforced after a while. Critical assets may have missing authentications or authorization checks, which might be a welcome sight for an attacker to easily infiltrate...
