In the current digital era, safeguarding privileged accounts is critical for maintaining the security and integrity of an organization’s IT infrastructure. Privileged Access Management (PAM) strategies are essential for controlling and monitoring access to sensitive systems, applications, and data. However, developing an effective PAM strategy requires more than just implementing tools, it demands a comprehensive approach that aligns with industry best practices. In this article, we will explore the key practices that organizations should follow to build a robust and efficient PAM strategy, ensuring that their most valuable assets are protected from potential threats.
The importance of Privileged Access Management
Privileged Access Management (PAM) is crucial in protecting an organization’s most sensitive information and systems. By controlling and monitoring access to privileged accounts, PAM minimizes the risk of unauthorized access, data breaches, and insider threats. An effective PAM strategy ensures that only authorized individuals have access to critical systems and that their actions are continuously monitored and logged. This not only strengthens overall security but also aids in regulatory compliance and reduces the potential impact of security incidents. Developing a strong PAM strategy is therefore essential for protecting the integrity and confidentiality of an organization’s digital assets.
Best practices for developing a good PAM strategy include implementing least privilege access, monitoring privileged accounts, adopting password security best practices, requiring multi-factor authentication, and regularly auditing privileges.
PAM best practices that companies should follow:
1. Implement least privilege access
Implementing least privilege access reduces an organization’s attack surface, minimizes insider threats, and prevents lateral movement. The principle of least privilege is a cybersecurity concept that grants users just enough network access to information and systems to do their jobs, and no more. By limiting access to privileged accounts and what those privileged accounts can do, organizations can reduce the potential entry points for unauthorized access and mitigate the impact of a data breach. To implement least privilege access, organizations must invest in a PAM solution. A PAM solution is a centralized tool that allows organizations to protect and manage privileged accounts.
2. Monitor privileged account activity
Companies must identify all privileged accounts within their network and manage them properly. When identifying privileged accounts, they should remove all unnecessary accounts to limit the number of privileged accounts. Organizations need to verify that privileged accounts have the right levels of access they need. Then they should check who is accessing these privileged accounts and how they are being used. This helps identify abnormal behavior of unauthorized users and immediately remove those users from the account. PAM solutions often include privileged account management and privileged session monitoring capabilities, allowing organizations to manage privileged users‘ permissions and monitor their activities.
3. Enforce just-in-time access
Just-in-time access elevates human and non-human user privileges in real time and limits session length for a specified time. This ensures that users and machines only have privileged access to resources when they need it. It limits the amount of access to privileged resources for a specific time and ensures that users do not have privileged access for longer than they need. This helps prevent abuse of privileged access by insider threats and prevents lateral movement within the network by unauthorized users. With a PAM solution, organizations can enforce just-in-time access to privileged accounts for temporary access.
4. Segmenting Networks
Network segmentation divides and isolates parts of a company’s network to control access to sensitive information. These segments are separated based on the type of sensitive resources and the users who need to access them. Companies can set up these network segments by using a PAM solution to monitor and manage access to them. This limits access across the entire network and only allows users to access the resources they need to do their jobs. Network segmentation prevents cybercriminals from moving laterally across an entire network and limits unauthorized users to only the network they have accessed. To protect the network even further, companies can create microsegments that isolate parts of the network within segments.
5. Adopting password security
To protect privileged accounts, organizations must adopt password security best practices. Cybercriminals try to use password-related attacks such as brute force attacks to crack the credentials of privileged accounts. Organizations must protect privileged accounts with strong and unique passwords. Strong passwords that are both long and complex make them difficult for cybercriminals to guess or crack. Each privileged account should have a unique password to prevent multiple accounts from being compromised through credential stuffing.
Organizations must also ensure that their passwords are properly stored in a password manager. A password manager is a tool that securely stores and manages passwords in a digitally encrypted vault. The password vault is protected by multiple layers of encryption and access is only possible with a master password. It helps prevent cybercriminals from using malware to steal passwords stored in unencrypted locations. A password manager also helps identify weak passwords and prompts users to strengthen them. Some password managers also allow employees to share passwords securely using methods such as one-time sharing. PAM solutions often have password management features that allow companies to understand their employees‘ password practices and enforce password security best practices.
6. Require MFA
Requiring multi-factor authentication (MFA) for privileged accounts is necessary to provide additional layers of security and ensure that only authorised users have access. MFA is a security protocol that requires users to perform more than one form of authentication to gain access to a service, application or database. MFA requires different types of authentication factors to allow users to verify their identity. These different types of authentication factors are something you know, something you have, something you are and where you are. For example, a user must provide something they know, such as a password or PIN, along with something they have, such as a security key or a time-based one-time password from an authentication app. PAM solutions with password management capabilities allow organisations to enforce the use of MFA for privileged accounts.
Conclusion:
Developing an effective Privileged Access Management strategy is crucial for safeguarding an organization’s sensitive assets and ensuring regulatory compliance. The best practices involve a comprehensive approach that includes identifying and classifying privileged accounts, implementing the principle of least privilege, and enforcing strong authentication mechanisms like multi-factor authentication (MFA). Additionally, continuous monitoring, regular audits, and automated tools are essential to detect and respond to anomalies swiftly. Organizations should also focus on user education and maintain a robust incident response plan. By integrating these practices, businesses can significantly reduce the risk of security breaches and enhance their overall cybersecurity posture.
