Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Privilege escalation attacks occur when bad actors exploit misconfigurations, bugs, weak passwords, and other vulnerabilities that allow them to access protected assets.

A typical exploit may start with the attacker first gaining access to a low-level privilege account. Once logged in, attackers will study the system to identify other vulnerabilities they can exploit further. They then use the privileges to impersonate the actual users, gain access to target resources, and perform various tasks undetected.

Privilege escalation attacks are either vertical or horizontal.

In a vertical type, the attacker gains access to an account and then execute tasks as that user. For the horizontal type, the attacker will first gain access to one or more accounts with limited privileges, and then compromise the system to gain more permissions to perform administrative roles.

Such permissions enable the attackers to perform administrative tasks, deploy malware, or do other undesirable activities. For example, they can disrupt operations, modify security settings, steal data, or compromise the systems such that they leave open backdoors to exploit in the future.

Generally, just like the cyber-attacks, privilege escalation exploits the system and process vulnerabilities in the networks, services, and applications. As such, it is possible to prevent them by deploying a combination of good security practices and tools. An organization should ideally deploy solutions that can scan, detect, and prevent a wide range of potential and existing security vulnerabilities and threats.

Best practices to prevent privilege escalation attacks

Organizations must protect all their critical systems and data as well as other areas that may look attractive to the attackers. All that an attacker requires is to penetrate a system. Once inside, they can look for vulnerabilities that they exploit further to gain additional permissions. Other than protecting the assets against external threats, it is equally important to put enough measures to prevent internal attacks.

While actual measures may differ according to the systems, networks, environment, and other factors, below are some techniques organizations can use to secure their infrastructure.

Protect and scan your network, systems, and applications

In addition to deploying a real-time security solution, it is essential to regularly scan all the components of the IT infrastructure for vulnerabilities that could allow new threats to penetrate. Towards this, you can use an effective vulnerability scanner to find unpatched and insecure operating systems and applications, misconfigurations, weak passwords, and other flaws that attackers can exploit.

scan your computer after infected

While you can use various vulnerability scanners to identify weaknesses in outdated software, it is usually difficult or not practical to update or patch all the systems. In particular, this is a challenge when dealing with legacy components or large scale production systems.

For such cases, you can deploy additional security layers such as web application firewalls (WAF) that detect and stop malicious traffic at the network level. Typically, the WAF will protect the underlying system even when it is unpatched or outdated.

Proper privilege account management

It is important to manage the privileged accounts and ensure that they are all secure, used according to the best practices, and not exposed. The security teams need to have an inventory of all the accounts, where they exist, and what they are used for. 

Other measures include

  • Minimizing the number and scope of the privileged accounts, monitoring, and keeping a log of their activities.
  • Analyzing each privileged user or account to identify and address any risks, potential threats, sources, and attacker’s intents
  • Major attack modes and prevention measures
  • Follow the least privilege principle
  • Prevent admins from sharing accounts and credentials.

Monitor user behavior

Analyzing user behavior can discover if there are compromised identities. Usually, the attackers will target the user identities which provide access to the organization’s systems. If they succeed to obtain the credentials, they will log into the network and may go undetected for some time.

Since it is difficult to manually monitor each user’s behavior, the best approach is to deploy a User and Entity Behavior Analytics (UEBA) solution. Such a tool continuously monitors user activity over time. It then creates a legitimate behavior baseline which it uses to discover unusual activities that are indicative of a compromise.

The resulting profile contains information such as location, resources, data files and services the user accesses and frequency, the specific internal and external networks, number of hosts as well as processes executed. With this information, the tool can identify suspicious actions or parameters that deviate from the baseline.

How user and entity behavior analytics works

Strong password policies and enforcement

Establish and enforce strong policies to ensure that the users have unique and hard to guess passwords. Additionally, using a multi-factor authentication adds an extra layer of security while overcoming the vulnerabilities that may arise when it is difficult to manually enforce strong password policies.

Security teams should also deploy the necessary tools such as password auditors, policy enforcers, and others that can scan systems, identify and flag weak passwords, or prompt for action. The enforcement tools ensure that users have strong passwords in terms of length, complexity, and company policies.

Organizations can also use enterprise password management tools to help users generate and use complex and secure passwords that comply with policies for services that require authentication.

Additional measures such as multi-factor authentication to unlock the password manager enhance its security further hence making it almost impossible for attackers to access the saved credentials. Typical enterprise password managers include Keeper, Dashlane, 1Password.

Sanitize user inputs and secure the databases

The attackers can use vulnerable user input fields as well as databases to inject malicious code, gain access, and compromise the systems. For this reason, security teams should use best practices such as strong authentication and effective tools to protect the databases and all kinds of data input fields.

A good practice is to encrypt all the data in transit and at rest in addition to patching the databases and sanitizing all user inputs. Additional measures include leaving files with read-only and giving the write access to the groups and users who require them.

Train users

The users are the weakest link in an organization’s security chain. It is therefore important to empower them and train them on how to perform their tasks securely. Otherwise, a single click from a user can lead to the compromising of an entire network or system. Some of the risks include opening malicious links or attachments, visiting compromised websites, using weak passwords, and more.

Ideally, the organization should have regular security awareness programs. Further, they should have a methodology to verify that the training is effective.
