developed by the National Information Assurance Research Laboratory of the NSA. They believe that creating a secure operating system is still a problem, but the NSA believes that a secure operating system can be accomplished through mandatory access control. Mandatory access control allows the administrator to manage access controls, which allows the administrator to define usage and access policy. The access policy indicates the access users have to files and programs. By using an access policy it

Network Access Control (NAC) is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network.[citation needed] NAC might integrate the automatic remediation process (fixing non-compliant nodes before allowing access) into the network systems, allowing the network infrastructure such as routers, switches and firewalls to work together with back office servers

that permission (perhaps indirectly) on to any other subject (unless restrained by mandatory access control)". Discretionary access control is commonly discussed in contrast to mandatory access control (MAC, sometimes termed non-discretionary access control). Occasionally a system as a whole is said to have "discretionary" or "purely discretionary" access control as a way of saying that the system lacks mandatory access control. On the other hand, systems can be said to implement both MAC and DAC

Asymmetric Encryption Encryption that uses two keys: if you encrypt with one you may decrypt with the other MD5 Message Digest 5. A hashing funciton used to provide integrity. MD5 uses 128 bits. A hash is simply a number created by applying the algorithm to a file or message at different times. The hashes are compared to each other to verify that integrity has been maintained.

Unit 2 Discussion 1: Identifying Layers of Access Control in Linux One of the most vital security tasks is to maintain control over incoming network connections. As system administrator, there are many layers of control over these connections. At the lowest level unplug network cables, but this is rarely necessary unless your computer has been badly cracked beyond all trust. More realistically, you have the following levels of control in software, from general to service-specific: Network

Scenario 1: (DAC) Discretionary Access Control. Being that the business is small and not in need of higher security measures, it would be the easiest to maintain and monitor for a small business. Scenario 2: (MAC) Mandatory Access Control. The employees primarily communicate using smartphones; which proves as a possible security risk. MAC is stronger than DAC but, still easily monitored for a small business; which makes this the top choice for Top Ads. Scenario 3: (RBAC) Role Based Access Control
