To protect a Program Control Block (PCB) from damage by other processes, operating systems implement various mechanisms such as memory protection and access controls. This typically involves isolating each process's memory space using techniques like virtual memory, ensuring that one process cannot directly access or modify another's PCB. Additionally, operating systems enforce strict access permissions, allowing only the kernel or designated system components to manipulate PCBs, thereby safeguarding them from unauthorized access or corruption.
Access controls can be classified into four main categories: physical controls, which restrict access to physical locations; logical controls, which regulate access to systems and data through software; administrative controls, which involve policies and procedures governing access; and technical controls, which use technology to enforce access restrictions, such as encryption and firewalls. Each category plays a crucial role in ensuring the security and integrity of information and resources.
A company should implement strict internal controls related to the management of its cash assets. This includes who is permitted to access cash assets, how cash can be spent, and how much cash should remain in accounts.

If users connect to the system by rote via dial-up line(e.g. from home), access should be restricted by a dial-up access control. Dial-up access controls prevent unauthorized acces from remote users that attempt to access a secured environment. These controls range from dialback controls to remove user authentication. Dial-back controls are used over dial-up telecommunication lines.
Technical controls are security measures implemented through technology to protect systems and data. Key families of technical controls include access controls (like authentication and authorization), encryption methods for data protection, intrusion detection and prevention systems, and secure network configurations (such as firewalls and VPNs). These controls are designed to detect, prevent, and respond to security threats effectively.
In security control, information systems are used to communicate between officers and store classified data. Ideally, information systems help to ensure security and make work easier for security officers.
