Life Cycle of Vulnerability Management

What is Vulnerability Management? Vulnerability management is a program that addresses common cybersecurity weaknesses in an organization's software, hardware, and network. These vulnerabilities can be exploited by hackers to steal data or do a brute-force attack. Therefore, vulnerability management helps to identify, close, and track these types of vulnerabilities and prioritize them in order of high risk to low risk. Life Cycle of Vulnerability Management 1. Discover This step involves the examination of operating systems, web services, hardware, web applications, and existing security patches to discover new vulnerabilities in the computer system. 2. Prioritize After the discovery of vulnerabilities, these are prioritized based on their nature which is informational, low, medium, high, and critical. The critical vulnerabilities should be dealt with first in the order of precedence. 3. Assess Now, assess all the vulnerabilities based on their severity. For example, low-risk vu

Controlled Substance and its Acts

What is Controlled Substance? A drug or any other substance which is strictly regulated by the government to prevent its abuse and addiction in normal people is known as a controlled substance. The control applies to the way the substance is manufactured, applied, managed, kept, and distributed. Control substances include opioids, stimulants, depressants, hallucinogens, and anabolic steroids. Certain controlled substances have great medical use like morphine, valium, etc they are available only by prescription from a licensed medical professional whereas other controlled substances don't have any medical applications like heroin, LSD, etc and they are completely banned in the country.  Different acts related to the regulation of controlled substances are as follows: 1. United States Controlled Substances Act Schedule 1 Drugs that have a high potential for abuse and do not have any medical application. For eg: Heroin, Lysergic acid diethylamide (LSD). Schedule 2 Drugs that lead to s

Forensic Chemistry and its Applications

What is Forensic Chemistry ? Forensic chemistry is the branch of forensic science that deals with the analysis of unknown chemical substances found at the scene of the crime like explosives, drugs, accelerants, poisons, etc. Forensic chemistry helps to link these substances with the suspect through different analytical techniques like HPLC, GC-MS, AAS, IR spectroscopy, FTIR, NMR Spectroscopy, etc . Moreover, the nature of these chemicals can also be identified by performing presumptive tests at the scene of the crime itself. Application of forensic chemistry In the arson case investigation, the potential accelerants used in arson present on the debris can be analyzed through techniques like gas chromatography-Mass spectroscopy. Gunshot residue present on the scene of the crime or the clothes of the victim/suspect can be analyzed under the scanning electron microscope. Forensic chemists examine evidence like blood stains, and urine to find traces of drugs, toxins, or poisons. Paper or t
