After assessing network strengths and weaknesses and building a properly segmented network, the next step to stronger security is to implement security controls. Cybercriminals are using sophisticated methods to attack specific targets and steal valuable information. The only defense against these attacks is an equally advanced security system where multiple layers work together to identify, expose, and extinguish threats.
Implementing a multi-layered threat prevention solution will provide several lines of defense to secure the most critical assets of an organization. These security protections are essential layers that work in tandem to find and track malicious threats as they move throughout the network.
Intrusion Prevention Systems
Hackers exploit vulnerabilities in software or operating systems to gain access into the network. Intrusion prevention systems (IPS) monitor and log suspicious activity while defending known vulnerabilities against these attacks.
Malware is designed to begin an attack, but anti-virus tools identify malware signatures and block infected files from being downloaded. Anti-virus solutions also scan URLs to prevent access to websites that are known to distribute malware.
Cybercriminals modify existing malware to have unrecognizable signatures, creating unknown malware that can bypass anti-virus solutions. Through sandboxing, files are examined in a secured environment to isolate and stop unknown malware before it enters the network.
Bots invade the network to spread malware and permit third-party control over computer systems. Anti-bot tools block outbound communication to command and controls centers while protecting the network against bot damages.
Hackers aim to infiltrate the network and locate confidential data so they can steal that information. Data loss protection exposes and blocks attempts to transfer stolen material outside the network, ensuring sensitive data and company assets stay secured.
There are a few key practices to keep in mind when constructing the necessary security controls for your network. Threat prevention layers should be integrated throughout the network to allow collaboration with the security infrastructure. All sensitive data should be encrypted to prevent any unwarranted disclosure in the event of a security breach. And, organizations must incorporate strong password policies and least privilege practices to ensure critical information is safeguarded against any malicious attempts to acquire them.
A multi-layered security solution will not only detect threats but also monitor and block an attack. Organizations need to design controls that provide fundamental security for critical assets and operations in order to maintain protection against advanced threats. Once you’ve applied the necessary security controls, you have completed the third step to Stopping the Next Massive Cyberattack.
This post is part of a series to encourage organizations to implement security solutions to avoid falling victim to cyberattacks. Cybercriminals can strike any organization at any time. We want to help you be protected. To learn about the Five Steps to avoid being the next data breach read our whitepaper, Stopping the Next Massive Cyberattack.
