Cybersecurity Homeland Security

Upon completion of the course, candidates should be able to explain the basic functions of the federal government, describe the forces that shape American policy and politics, and be better prepared to participate in America’s civic institutions. Applied Algebra is designed to help you develop competence in working with functions, the algebra of functions, and using some applied properties of functions. You will start learning about how we can apply different kinds of functions to relevant, real-life examples.

Intrusion Detection System products are designed to detect network attacks in-progress and assist in post-attack forensics, while audit trails and logs serve a similar function for individual systems. As with physical security, the motivations for breaches of computer security vary between attackers. Some are thrill-seekers or vandals, some are activists, others are criminals looking for financial gain. State-sponsored attackers are now common and well resourced but started with amateurs such as Markus Hess who hacked for the KGB, as recounted by Clifford Stoll in The Cuckoo's Egg.

Identifying attackers is difficult, as they may operate through proxies, temporary anonymous dial-up accounts, wireless connections, and other anonymizing procedures which make back-tracing difficult - and are often located in another jurisdiction. If they successfully breach security, they have also often gained enough administrative access to enable them to delete logs to cover their tracks. In order to ensure adequate security, the confidentiality, integrity and availability of a network, better known as the CIA triad, must be protected and is considered the foundation to information security. To achieve those objectives, administrative, physical and technical security measures should be employed. The amount of security afforded to an asset can only be determined when its value is known. Determination of controls based on risk assessment, good practices, finances, and legal matters.

They often include detailed logging, and may include intrusion detection and intrusion prevention features. They are near-universal between company local area networks and the Internet, but can also be used internally to impose traffic rules between networks if network segmentation is configured. A DPO is tasked with monitoring compliance with the UK GDPR and other data protection laws, our data protection policies, awareness-raising, training, and audits. This position may also include taking on some of the tasks of a security analyst in smaller organizations. There are a few critical voices that question whether cybersecurity is as significant a threat as it is made out to be.

For example, in 2007, the United States and Israel began exploiting security flaws in the Microsoft Windows operating system to attack and damage equipment used in Iran to refine nuclear materials. Iran responded by heavily investing in their own cyberwarfare capability, which they began using against the United States. Between September 1986 and June 1987, a group of German hackers performed the first documented case of cyber espionage. The group hacked into American defense contractors, universities, and military bases' networks and sold gathered information to the Soviet KGB. The group was led by Markus Hess, who was arrested on 29 June 1987.

Endpoint security software aids networks in preventing malware infection and data theft at network entry points made vulnerable by the prevalence of potentially infected devices such as laptops, mobile devices, and USB drives. Cryptographically secure ciphers are designed to make any practical attempt of breaking them infeasible. Symmetric-key ciphers are suitable for bulk encryption using shared keys, and public-key encryption using digital certificates can provide a practical solution Cybersecurity for the problem of securely communicating when no key is shared in advance. Access authorization restricts access to a computer to a group of users through the use of authentication systems. These systems can protect either the whole computer, such as through an interactive login screen, or individual services, such as a FTP server. There are many methods for identifying and authenticating users, such as passwords, identification cards, smart cards, and biometric systems.

The course covers widely used penetration testing techniques that focus on planning and scoping, information gathering, vulnerability identification, and attacks and exploits. The course also introduces students to tools that can be used for penetration testing, reporting, and communication. Security information professionals have the role and responsibility for knowing and applying ethical and legal principles and processes that define specific needs and demands to assure data integrity within an organization.

These weaknesses included replay attacks and a vulnerability that allowed hackers to alter unencrypted communications sent by users. Since the Internet's arrival and with the digital transformation initiated in recent years, the notion of cybersecurity has become a familiar subject in both our professional and personal lives. Cybersecurity and cyber threats have been consistently present for the last 50 years of technological change. In the 1970s and 1980s, computer security was mainly limited to academia until the conception of the Internet, where, with increased connectivity, computer viruses and network intrusions began to take off.

Dr. Chutima Boonthum-Denecke from Hampton University’s Computer Science Department introduced the Secretary and facilitated a Q&A to close the program.
