BeyondTrust Linux Privilege Escalation

It is common knowledge that Linux and Unix system are prime targets for external attackers and unverified insiders as well.

You’re susceptible to breach if you share login credentials, or approve access that is not monitored or allows files and sessions to be accessed unchecked. Root access to privileged credentials means attackers will find it easy to operate on a low profile as they access critical data and systems.

And risk also spread as the attack points multiply, perimeters are crossed, cybercriminals get bolder, and compliance requirements increase. So, how do you limit root access, credential sharing, meet compliance requirements, and guarantee accountability without impeding workflow?

The Risk of Not Protecting Unix/Linux Privileged Accounts

Upgrading the privilege means a hacker has gained access to special entitlements that they should not have and are not entitled to. A cybercriminal can use these privileges to execute malicious activities such as accessing private organization information, deleting files, or installing bad programs or applications like ransomware or viruses on your enterprise network, causing all types of issues.

Actions like these usually happen when your network has a bug that gran5s access to be bypassed or if your system architecture is compromised with design flaws. Another reason can be if the business owner or an employee makes an error that grants the attacker unfettered access to your Linux/Unix system.

Once an attacker gains to your system, here are two options for the attacker to approach privilege escalation. Namely:

• Vertical Privilege Escalation: Otherwise known as privilege escalation, in this scenario, the attacker uses a lower privilege he or she has access to and accesses content or functions reserved for higher applications or privileged users
• Horizontal Privilege Escalation: This second form of privilege escalation is when a cybercriminal uses typical user privileges to access content or function reserved for fellow normal users, in a bid to escalate his or her privileges.
