In law enforcement, computer forensics professionals may work for local police departments, state police departments, or the Federal Bureau of Investigation. They may go to the scene of incidents, gather evidence, investigate the evidence, and write reports. They may also provide testimony for criminal cases in court. Individuals who specialize in the forensic study of computers may also be called “cyber investigators”, “cyber cops”, or “digital detectives”.

Computer forensics experts investigate crimes such as identity theft, credit card fraud, intellectual property theft, threats/harassment, pedophilia, and unauthorized computer system intrusion. These computer crimes or “cyber crimes” constitute a significant risk to individuals, companies, and governments. Cyber crimes result in tens of millions of dollars of dollars in losses each year.

Computer forensics examiners need a wide range of technical skills and knowledge. They must have expertise in network security, protocols, software, computer file formats, routing, cryptology, reverse software engineering, password cracking, and diagnostic techniques. In addition to technical skills, professionals in this field must have good oral and written communication skills, understand and comply with investigation procedures, work under tight deadlines, have problem solving abilities and be creative and persistent in the pursuit of evidence.

Experts in this field may also be involved in crimes that were not directly committed via computer. There may be information stored on a computer or storage device that is important for the case. For example, e-mail evidence can be used in cases against robbery and homicide suspects. Computer forensics experts are needed in these cases, as there are very specific procedures that must be followed for digital information to be presented as valid evidence.

Most individuals have encountered a police officer at least once in their lives. Law enforcement officials maintain peace and order in society. Law enforcement officials are commonly known as police or police officers

The functions of uniformed police officers include traffic control, active crime response, and crime prevention. The officers that belong to this group are easily identifiable by the public.

Plainclothes police detectives do not wear uniforms. They engage in investigative work and are usually involved in a single case for long periods of time. They gather information partly by blending in with the crowd. Unless it’s absolutely necessary, they usually do not reveal that they are law enforcement officers. At times, they actually take on false identities during undercover operations.

There are also specialized groups within the department of law enforcement. The bomb squad is a group that deals primarily with explosives. A special unit called the narcotics department, or the NARCS, specializes in cases that deal with illegal substances. The most important police officers in terms of field operations are the members of the Special Weapons and Tactics (SWAT) teams. The members usually carry smaller, more powerful weapons that allow them to defend themselves during violent situations. They are also equipped with non-lethal weapons such as tear gas, concussion grenades, and rubber bullets, as well as protective bulletproof vests.

Even law enforcement officials have their own watchdogs. The Department of Internal Affairs deals with the overseeing investigations within the department. The scope of their work is limited to bribery, graft, and other methods and cases of internal corruption.
