5 Vulnerabilities SOC Teams See Most Often This Year

Over the past year, our SOC (Security Operations Center) team has monitored systems for dozens of client organizations, and found that most incidents weren't caused by sophisticated, cutting-edge threats, but by basic vulnerabilities that aren't hard to fix. This article rounds up the 5 most common vulnerabilities we see, along with what you can do about them right now.

1. Weak Passwords and Password Reuse

Accounts with easily guessed passwords, or the same password reused across multiple systems, remain the number one cause of breaches. Once a password leaks from one service, attackers immediately try it against other systems (credential stuffing).

• Enforce a strong password policy and turn on Multi-Factor Authentication
• Audit inactive accounts and disable them immediately

2. Unpatched Systems

Servers and devices running outdated versions often carry vulnerabilities that are already publicly disclosed. Attackers only need to scan for them and use off-the-shelf tools to get in.

Over 60% of the incidents we detected involved vulnerabilities for which a patch had already been available for more than 3 months

3. Configurations That Are Exposed More Than Necessary

Management ports open to the internet, unencrypted databases, or storage buckets set to public — these are all doors left wide open.

4. Phishing and Employee Deception

Deceptive emails still work, because they target "people," not systems. Security awareness training and simulated phishing exercises can significantly cut click-through rates.

5. Excessive Access Privileges

Many users hold administrator-level privileges they don't actually need. When one of those accounts is compromised, the damage spreads immediately — which is why the principle of least privilege matters.

If your organization doesn't yet have a 24-hour monitoring team, SOC as a Service lets you detect and respond to threats without having to build the team yourself.
