What is an Advanced Persistent Threat (APT)?

The digital age has brought about numerous advancements, but it has also ushered in an era of increased cyber threats. One such threat that stands out due to its complexity and potential damage is the Advanced Persistent Threat (APT). These threats are not ordinary cyber-attacks; they are sophisticated, relentless, and highly damaging.

What is an advanced persistent threat?

An Advanced Persistent Threat (APT) is a network attack in which an unauthorized person gains access to a network and stays there undetected for a long period. The intent behind APTs is usually to monitor network activity, steal data, or cause disruption rather than to cause immediate damage. APTs are often sponsored by nation-states or criminal organizations, making them highly organized and extremely dangerous.

Characteristics of an APT attack

Several characteristics set APT attacks apart from other cyber threats. Firstly, APTs are highly targeted, focusing on specific organizations or individuals. This focus allows the attacker to remain undetected for longer periods.

Secondly, APTs are persistent. Unlike other attacks that cease once detected, APTs continue to evolve and adapt, making them difficult to eliminate completely.

Lastly, APTs are advanced. They employ sophisticated techniques and malware to penetrate defenses, often exploiting zero-day vulnerabilities that have not yet been patched.

Common targets for APT attacks

Targets for APT attacks are typically organizations with high-value information. These include government agencies, defense contractors, and large corporations. However, smaller businesses and individuals are not immune, especially if they are linked to larger organizations or possess valuable data.

5 steps for preventing an APT Attack

  1. Software updates and patching: It is of utmost importance that software is updated and patched on a regular basis. By following patch management best practices, IT professionals prevent the exploitation of vulnerabilities by cyber attackers.
  2. Monitoring of network activity: Unusual activity within a network can be detected through constant network monitoring. This allows for the identification of possible threats and the prevention of unauthorized access.
  3. Education of employees: Knowledge is power – and in this case, protection. Employees must be educated and continually trained on the dangers of phishing attempts and how to avoid them.
  4. Implementation of a robust incident response plan: A comprehensive incident response plan is pivotal in the fight against APT attacks. This plan should outline the steps to identify, contain, eradicate, and recover from an attack. Additionally, it should also include preventive measures to thwart future attacks.
  5. Regular security audits and risk assessments: Regular security audits and risk assessments are necessary to identify potential vulnerabilities and gaps in the security infrastructure. These should then be addressed promptly.
  6. Use of advanced threat protection tools: To combat advanced threats, advanced tools are needed. Deploying advanced threat protection tools that use machine learning and AI can help identify and mitigate threats before they cause damage.

Advanced persistent threat: What IT teams can do about it

Although Advanced Persistent Threats (APTs) represent a significant threat in the digital age, IT teams can minimize the risks by understanding their nature and implementing robust prevention measures. As long as you are aware of the threat and use the right security and RMM tools, you have the ability to prevent security threats from overtaking your business.
