A defense is a strategy used to protect something from an opponent. There are many different types of defense, including national defense, a football team's defensive strategy, and the services of a defense lawyer. This article explores several of the most common forms of defense and what these strategies can do to protect you and your business. In addition to defense in the home, we'll also look at physical security flaws and the importance of layered security.
Insanity defense
An insanity defense is a common legal tool used to help a defendant escape a criminal conviction. Typically, a defendant is considered guilty but mentally ill if he or she was incompetent at the time of the crime or when the trial was conducted. However, the insanity defense is not a universally available option. Some jurisdictions, such as Maryland and Connecticut, have laws allowing guilty but mentally ill defendants to plead guilty. While this option is not necessarily a good one for most defendants, it is a viable alternative for a defendant who is unable to understand the crime.
The first component of an insanity defense looks to determine whether the defendant was incapable of reasoning or understanding. In other words, was the defendant unable to recognize that his or her actions were wrong? If so, the defendant may be deemed insane. A paradigmatic example of incapacity would be a deific decree. In addition, a defendant may also be legally insane if they are incapable of communicating or interacting with their attorney.
Another type of insanity defense is volitional. Volitional insanity claims that the defendant was not capable of self-control when the act was committed. This defense is most common in cases involving revenge, retribution, or a motivated impulse. For example, a mother who shoots her child abuser may argue that she was not guilty due to insanity. However, this form of insanity defense is only available in a handful of states.
An insanity defense expert must explain the defendant's inability to distinguish right from wrong. Unlike the other types of insanity defenses, voluntary intoxication is not a viable defense in criminal trials. Texas is the only state that allows temporary insanity as a defense. If a defendant has been convicted, the state can argue that the defendant exhibited insanity and is not responsible for his actions.
Layered security
In information security, the concept of "defense in depth" is often used. This concept involves implementing multiple layers of security controls throughout an IT system. For example, a network should have two layers of security controls, and a single weak link could be compromised and exposed to attack. Defense in depth is critical in the case of information systems and can help protect against a cyberattack. Here are four reasons why you should implement layers of security throughout your IT system.
Layered security is a common security strategy for many businesses. The principle behind this approach is similar to that of classic heist movies. A burglar must get past multiple layers before reaching his target's valuables. The first layer of defense is a locked door, followed by an intrusion detection system. A third layer of defense may include guards inside the building, video cameras, and other measures. By adding multiple layers of security to a network, the attack vector is limited and eventually stymied.
The best layered security strategy includes a combination of different types of technologies. For example, it includes anti-virus and anti-malware programs, hashing and encryption systems, and multi-factor authentication systems. In addition, it includes threat assessment tools, detailed audit logs of network activity, and machine learning tools. This combination of technologies makes network security even more effective. This layered security approach is one of the best ways to protect a business.
While layered security is not the best security strategy, each element of this strategy remains important. Layered security isn't an exact science. Many aspects of security are interrelated and each layer complements one another. The overall goal of layered security is to minimize the network attack surface. In short, layered security protects your network from various attack angles. So, don't assume that any solution in security architecture will be perfect. Instead, use multiple solutions that cover each other's weaknesses.
Defense-in-depth strategy
Cyber security strategies like a Defense-in-depth strategy require layered defenses to protect sensitive information technology assets. This multi-layered approach consists of multiple layers of security controls and technology, with each layer allowing for another to fail. A single-layer security approach does not provide enough protection against sophisticated cyber attacks, and many companies use multiple layers of defense to avoid such a situation. While a simple defense-in-depth strategy might seem more appealing at first, it is important to remember that a single layer of protection is not going to keep up with the increasing sophistication of cyber attacks.
Security should be implemented in three levels: physical, technical, and administrative. Physical controls include locking down facilities and enforcing employee password policies. Technical controls involve securing your network and its hardware and software. Third-party security must extend to cloud providers and third-party vendors. The latter two layers of defense require advanced technical controls to protect sensitive data and information. And finally, a Defense-in-depth strategy must include physical, human, and cyber threats.
One of the most important components of a Defense-in-depth strategy is a defense model that takes into account the human element. The human element is increasingly a part of the equation, and it's important to have an effective security strategy for every aspect of our lives. A Defense-in-depth strategy will keep your data safe even when human error or security updates are overlooked. This method is also effective for protecting your data in the event of an attack.
Having multiple layers of security on a network allows administrators the time to deploy countermeasures if necessary. Antivirus software and firewalls are just the beginning. The next layer of security is your firewall, which should block further entry. The idea behind a Defense-in-depth strategy is to prevent a threat from getting through each layer, which may be a challenge without proper defenses. However, there is no such thing as a perfect defense system.
Physical security flaws
Several physical security threats exist in the world today, and each presents a unique set of challenges. Understanding them is the first step to determining how to best protect your properties. Physical security threats include threats to your property perimeter, the way you use your building, and potential damage to resources and information. Whether these threats are natural or man-made, it is important to understand each threat and devise a security strategy that takes these vulnerabilities into consideration.
Attackers have shown that physical security is an open invitation for a breach. For example, an attacker does not have to breach a heavily guarded server room to access sensitive files, such as employee records and personnel files. A hacker can access PCs throughout a building, wire money out of the company, and steal confidential files. Even though cybersecurity protection and extensive digital controls are required to protect against such attacks, physical security flaws are an easy way to bypass these measures.
Many attackers leverage physical threat vectors to get around digital controls. For example, a rogue employee may plant an infected USB drive in a public location, then load the infected drive onto the network. Another attacker might break into the server room and install rogue devices. If the internet drop line goes outside the building, an attacker can cut it and intercept data. A hacker can also cut the internet drop line to disrupt operations.
Small businesses often maintain their own data centers in rooms small enough to protect from unauthorized access. Physical cyber security defenses work hand in hand with information and software security measures to provide a strong foundation. These physical security measures are essential for small businesses and other organizations with limited budgets. Physical security defenses should be complemented with cyber security to avoid the vulnerability of sensitive information. So, how do you go about securing your data center?
Sources of threats
The latest cybersecurity breach involved the European aerospace company Airbus. The hacking group Team Snatch broke into the company's computer systems over a four-month period and demanded ransom in exchange for sensitive government data. The stolen data appeared on the dark web and the government suspended the company's supplier following the breach. Regardless of the cause, preventing these attacks is essential to ensuring that defense contractors don't fall victim to the same fate.
These sophisticated attacks often target national security. They can even shut down electricity in an enemy's territory. The line between state-sponsored and criminal organizations is blurred. Most cyber-attacks are purchased on the "dark web," a criminal segment of the Internet where aspiring hackers can purchase malware and ransomware. Cybercrime is an increasingly serious concern and acts as a multiplier of threats. In fact, it is estimated that more than 100 million people are exposed to internet scams and malicious websites.
For a comprehensive threat model, a project team and stakeholders must define the threat scope. The scope of the model should be defined according to the system architecture and security perimeters, as well as the various data points and data flows that make up the system. Threat models can be a simple data flow diagram or a more complex process-flow-based model. By gathering threat intelligence, an organization can better understand the different types of cyberthreats it faces and more effectively defend against them.
The modern cyber threat landscape is increasingly complicated to combat, as more people store their personal information on personal devices. As a result, it is easier for cyber attackers to find an entry point to a target organization. A data breach has several potential sources, including incomplete deletion of data and vulnerable cloud apps. In addition to these, work from home facilities have become widespread. Many employees are using unpatched devices, which can pose unique IT security risks.
