EPM for Efficient Attack Surface Reduction
Unsecured endpoints are gateways to ransomware attacks. When malware gains access to an endpoint device, it can carry on lateral movement towards other endpoints or vertical movement towards target servers to further intrude into privileged accounts and disrupt networks.
Gaps in endpoint protection can mean catastrophic breaches and operational downtimes.
Did you know?
“Approximately 80% of successful breaches result from unique or undiscovered zero-day attacks. It means every endpoint such as a workstation, a laptop, or a desktop is potentially at risk.”
The solution to this problem starts with reinforcing the building blocks of an enterprise, i.e., endpoints. This is where Endpoint Privilege Management (EPM) enters the picture.
EPM controls and oversees users’ and applications’ access rights and privileges on endpoints. By adhering to the Principle of Least Privilege (POLP), EPM ensures that individuals and applications have only the permissions necessary for their tasks.
EPM helps with enterprise attack surface reduction. Having a powerful EPM strategy reduces the risk of unauthorised users performing critical actions on enterprise devices, such as application installation or user account administration.
In this blog, we will focus on how attack surfaces are formed and the role of EPM solutions in safeguarding endpoints and its helpfulness in attack surface reduction.
What Does Attack Surface Mean in Enterprise Security?
The attack surface is the total number of attack vectors through which an unauthorised user can attempt to enter data into or extract data from an enterprise environment.
First, let’s understand the challenges surrounding endpoints and, later, delve into understanding the other attack surface components.
The endpoint attack surface consists of potential vulnerabilities that can act as entry points for attackers. Some of the entry points are:
- Operating system flaws
- Outdated or vulnerable applications
- Weak user credentials
- Unsecured network interfaces
- Connected peripheral devices
- Misconfigured settings
If not effectively managed, web browsers, their extensions, and endpoint security solutions contribute to the attack surface. To mitigate these risks, organisations must regularly update and patch systems. In addition, it is always good to:
- Apply the principle of least privilege
- Implement strong Multi-Factor Authentication
- Use secure network configurations
- Deploy comprehensive EPM solutions
- Maintain continuous monitoring.
By effectively managing the above elements, enterprises can succeed in attack surface reduction with an enhanced cybersecurity posture.
The Value of Endpoints and the Significance of Securing Them
Endpoints, with all the value and control they hold in a network, are vulnerable to threats.
Common Endpoint Vulnerabilities
Securing endpoints requires a comprehensive approach that includes regular updates, strong authentication practices, vigilant monitoring, and user training. Addressing these vulnerabilities is essential to maintaining the integrity and security of the entire network. Here are some of the common vulnerabilities that can make endpoints susceptible to cyberattacks.
- Malware Infection: Malicious software can compromise endpoints, leading to data theft, system damage, or unauthorised access.
- Unpatched Software: Unpatched software and operating systems expose endpoints to known vulnerabilities that threat actors can easily exploit.
- Weak Authentication: Poor authentication methods, such as weak passwords, increase the risk of unauthorised access.
- Misconfigured Endpoints: Incorrectly configured devices may expose sensitive data or create backdoors for threat actors to exploit.
- Insider Threats: Employees with malicious intent or carelessness can cause significant harm by misusing endpoint access.
- Data Leakage: Sensitive data can leak from secure endpoints, leading to breaches.
- Unauthorised Device Usage: Unauthorised devices connecting to the network introduce vulnerabilities.
Endpoint Privilege Management and its Components
EPM solutions manage user privileges on endpoints. Their primary objective is to help in controlling endpoint access, enforce application policies, and allow users to elevate privileges on-demand.
Key components of EPM include privilege management, application control, access controls, and continuous monitoring and auditing of user activities. Implementing EPM effectively involves setting clear access policies, deploying tools, and regularly reviewing privilege levels to enhance security, reduce breach risks, and improve compliance with regulatory standards.
- Least Privileged Access
Least Privileged Access is a fundamental principle of EPM. It ensures that users and applications have the minimum level of access necessary to perform their functions. Restricting privileges reduces the potential damage from compromised accounts or malware.
Key Aspects:
- Minimising Access Rights: Users grant only the permissions they need.
- Attack Surface Reduction: Limiting privileges lowers the number of potential entry points for attackers.
- Enhancing Security Posture: Enforcing the least privilege helps prevent unauthorised access and data breaches.
2. Application Control
Application control involves managing which applications can run on endpoint devices. This component of endpoint privilege management helps prevent the execution of unauthorised or malicious software by establishing policies that control application usage.
Key Aspects:
- Whitelisting: Only approved applications can run.
- Blacklisting: Block all unknown, malicious, or unwanted applications.
- Monitoring and Logging: Tracking application usage to detect suspicious activities.
3. Privilege Elevation Management
Privilege elevation management focuses on temporarily enhancing users’ privileges when necessary. This component ensures that users grant access only for specific tasks and durations, reducing the risk of misuse.
Key Aspects:
- Just-in-Time Access: Providing elevated privileges only when needed.
- Time-bound Access: Limiting the duration of elevated privileges.
- Approval Processes: Requiring authorisation for privilege elevation requests.
- Elevate application on-demand: User requests application installation depending upon organisational requirements.
- Controlled and Temporary Admin access: User can ask for short team admin access by justifying the need.
4. Offine Scenario:
The offline scenario in EPM involves managing administrative rights and privileges when an endpoint is not connected to the network.
Key aspects:
- On-time access: Provides offline code feature for on-time access.
- Local cache: EPM system cached all the policies given by administrator to monitor activities offline.
- Predefined policies: Policies are applied locally to ensure least privilege access without network connection.
5. Remove and Continuously Monitor Administrator Rights
Sectona EPM mitigates the risk of malicious software installation and backdoor creation by removing such privileges while ensuring uninterrupted user productivity through tailored policies.
Key aspects:
- Rights removal: Removes local administrator rights from endpoints when user creates a backdoor user.
- Prevention: Prevents the installation of unapproved software and the creation of backdoor accounts.
- Maintainability: Maintains UX and productivity by allowing admins to set policies enabling the use of necessary applications.
