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 (principle of least privilege). For example a Web server that runs as the administrative user (root or admin) can have the privilege to remove files and users that do not belong to it. 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 file system functions, cannot compromise the system it runs on unless the security around it is in itself also flawed. Often the easiest way to break the security of a client/server system is not to go head on to the security mechanisms but instead to go around them. A man in the middle attack is a simple example of this, because you can use it to collect details to impersonate a user. Which is why it is important to consider encryption, hashing, and other security mechanisms in your design to ensure that information collected from a potential attacker won't allow access. Another key feature to client-server security design is general good-coding practices. For example, following a known software design structure such as client and broker can help in designing a well built structure with a solid foundation. Furthermore that if the software is modified in the future it is even more important that it follows a logical foundation of separation between the client and server. This is because if a programmer comes in and cannot clearly understand the dynamics of the program they may end up adding or changing something that can add a security flaw. Even with the best design this is always a possibility, but the better standardized the design the less chance there is of this occurring.

United States Cyber Commands

Cyberwarfare in the United States is the United States Cyber Commands military strategy of proactive cyber defense and the use of cyberwarfare as a platform for attack. The United States Department of Defense sees the use of computers and the Internet to conduct warfare in cyberspace as a threat to national security. The Joint Forces Command issued a statement: Cyberspace technology is emerging as an instrument of power in societies, and is becoming more available to a country's opponents, who may use it to attack, degrade, and disrupt communications and the flow of information. With low barriers to entry, coupled with the anonymous nature of activities in cyberspace, the list of potential adversaries is broad. Furthermore, the globe-spanning range of cyberspace and its disregard for national borders will challenge legal systems and complicate a nation's ability to deter threats and respond to contingencies.

The five pillars is the framework for the United States military strategy for cyberwarfare. The first pillar is to recognize that the new domain for warfare is cyberspace similar to the other elements in the battle space. The second pillar is proactive defenses as opposed to passive defense. Two examples of passive defense are computer hygiene and firewalls, which detect approximately 70 to 80 percent of cyber attacks. The balance of the attacks requires active defense using sensors to provide a rapid response to detect and stop a cyber attack on a computer network. This would provide military tactics to hunt down and attack an enemy intruder. The third pillar is critical infrastructure protection (CIP) to ensure the protection of critical infrastructure. The fourth pillar is the use of collective defense, which would provide the ability of early detection and to incorporate them into the cyberwarfare defense structure. The fifth pillar is to maintain and enhance the advantage of technological change. This would include improved computer literacy and increasing artificial intelligence capabilities.
