Introduction
As cyber threats become more advanced and targeted towards organizations, advanced persistent threats (APTs) have emerged as one of the most significant concerns for security teams. APTs are stealthy, sophisticated attacks that infiltrate networks and remain undetected for extended periods to steal data or disrupt operations. Protecting against APTs requires a layered defense with advanced threat protection capabilities. In this article, I will provide an in-depth review of leading advanced persistent threat protection solutions in the market.
Overview of APTs
Before reviewing APT protection solutions, it is important to understand what APTs are and what makes them different from other threats.
What are APTs?
APTs are cyber attacks that are directed at specific organizations and entities. The key characteristics of APTs include:
-
Targeted – APTs are highly customized to target specific organizations and access valuable data. Attackers conduct reconnaissance to study the victim’s infrastructure before launching the attack.
-
Sophisticated – APTs employ advanced, customized tools and evasion techniques to circumvent security defenses and avoid detection. Attackers are highly-skilled and well-resourced.
-
Stealthy – APTs are designed to infiltrate networks undetected over an extended period, sometimes years. The goal is to maintain persistent access while remaining unnoticed.
-
Multi-stage – APTs progress through various stages such as reconnaissance, initial compromise, command and control, lateral movement, and data exfiltration. Each stage utilizes different tactics and tools.
Differences from other cyber threats
Unlike commodity malware and automated attacks, APTs are handcrafted for specific targets and executed by determined human attackers. Their stealthy and patient nature makes them challenging to detect with traditional security tools.
Capabilities Required for APT Protection
To provide effective protection against advanced persistent threats, security solutions need to have the following key capabilities:
Prevention
-
Threat intelligence – Up-to-date threat intelligence feeds to block known APT malware, sources, and behaviors.
-
Behavioral analytics – Analyze behavior patterns and anomalies to detect malicious actions associated with APTs across the kill chain.
-
Sandboxing – Safely inspect and detonate suspicious files and URLs to uncover advanced malware used in APTs.
-
Anti-evasion techniques – Prevent attackers from bypassing security defenses through evasion tactics.
Detection
-
Continuous monitoring – Monitor all traffic and activities across endpoints, network, users, and data to identify signs of compromise or malicious behavior.
-
Endpoint detection and response – Detect, investigate, and remediate threats on endpoints.
-
Deception technology – Deploy traps and lures to detect lateral movement and reconnaissance.
Response
-
Threat hunting – Proactively hunt for advanced threats and data exfiltration across the environment.
-
Automated response and containment – Quickly isolate infected hosts and compromised user accounts to prevent spread and data loss.
-
Threat intelligence enrichment – Gain insights into malware and adversary tactics, techniques, and procedures (TTPs).
-
Incident response orchestration – Streamline and automate the incident response process.
