Peace Security
Security Peace
Computer security is a branch of computer technology known as information security as applied to computers and networks. The objective of computer security includes protection of information and property from theft, corruption, or natural disaster, while allowing the information and property to remain accessible and productive to its intended users. The term computer system security means the collective processes and mechanisms by which sensitive and valuable information and services are protected from publication, tampering or collapse by unauthorized activities or untrustworthy individuals and unplanned events respectively. The strategies and methodologies of computer security often differ from most other computer technologies because of its somewhat elusive objective of preventing unwanted computer behavior instead of enabling wanted computer behavior.
Peace Secuirty
Peace is a state of harmony, the absence of hostility. This term is applied to describe a cessation of violent international conflict; in this international context, peace is the opposite of war. Peace can also describe a relationship between any parties characterized by respect, justice, and goodwill. Peace can pertain to an individual relative to her or his environment, as peaceful can describe calm, serenity, and silence. Peace Iraq peace in Iraq security Iraq security World Wide. Security is the condition of being protected against danger or loss. In the general sense, security is a concept similar to safety. International security consists of the measures taken by nations and international organizations to ensure mutual survival and safety. Information security is the process of protecting data from unauthorized access, use, disclosure, destruction, modification, or disruption. The terms information security, computer security and information assurance are frequently used interchangeably.
Secure By Design
Secure by design, in software engineering, means that the software has been designed from the ground up to be secure. Malicious practices are taken for granted and care is taken to minimize impact when a security vulnerability is discovered or on invalid user input.
Generally, designs that work well do not rely on being secret. It is not mandatory, but proper security usually means that everyone is allowed to know and understand the design because it is secure. This has the advantage that many people are looking at the code, and this improves the odds that any flaws will be found sooner. Of course, attackers can also obtain the code, which makes it easier for them to find vulnerabilities as well.
Also, it is very important that everything works with the least amount of privileges possible . For example a Web server that runs as the administrative user can have the privilege to remove files and users that do not belong to itself. Thus, a flaw in that program could put the entire system at risk. On the other hand, a Web server that runs inside an isolated environment and only has the privileges for required network and filesystem functions, cannot compromise the system it runs on unless the security around it is in itself also flawed.
A perfect authentication system for logins does not allow anyone to log in at all, because the user could be a threat to the system. However, some designs can never be perfect. Passwords, biometrics, and such are never perfect.
