Determine whether hacking into a website is ever justifiable by applying your theory to a real case where someone hacked into a system, including the company name and details. In general, hacking or more specifically cracking is not justifiable due to the negative connotations associated with the term. Hackers are generally classified into three categories: white hat, black hat or gray hat (Arnone, 2005). White hats are personnel often employed to find holes in, penetrate or exploit a security system so that the company can take corrective action. Black hats are generally associated with malicious activities (cracking) such as the development and distribution of viruses, worms, theft, or damage to a system. Gray hats are somewhere between white and gray hats. Arnone discusses how the federal government is using hackers to test their security measures and learn how to protect their systems by understanding how hackers operate and gain access to network systems (Arnone, 2005). The white hat hacker proved himself by showing a company where security vulnerabilities lie. White hackers are also in demand. They are hired by consultants at many Fortune 500 companies to identify external and internal weaknesses and report them so that those holes can be closed (Wiles, 2008). There are some cases where hacking may be justified. Hacking for national security can be justified even if controversial. The military has been using hacking techniques for decades. While not specifically tied to a computer, they deceived the enemy using fake radio broadcasts, such as preparations for the invasion of Normandy in World War II. The military has been monitoring radio conversations via wiretaps... middle of paper... ever-evolving threats and increasingly sophisticated cybercriminals, AT&T works to stay one step ahead. The company's sophisticated network monitors, probes, and algorithms identify known or suspected viruses, worms, and other Internet attacks, often destroying them before they reach an organization” (AT&T, 2011). AT&T emphasizes individual vigilance regarding your personal account information. AT&T will never ask for account information via email or over the phone. Should you receive such requests, please treat them as fraudulent. AT&T has alerted the Federal Bureau of Investigation's Cyber ​​Task Force to assist and review our security systems to prevent future breaches. We consider this breach very serious and maintaining your trust is our top priority and we apologize for the incontinence of this security breach caused. Kind regards,
