Cybersecurity refers to the processes and methodologies designed and enforced mainly to safeguard print, electronic, and other kinds of confidential, personal, and sensitive data or knowledge from unauthorized access, misuse, disclosure, destruction, modification, or disruption. Cybersecurity is defined as the body of technologies, processes, and practices designed solely for protecting networks, computers, programs, and information from attack, harm, or unauthorized access.
Use of Cybersecurity in Information Systems
Cybersecurity plays the most important role for your sensitive information to keep it confined within your reach. It is a procedure of defending your computers, mobile devices, servers, electronic systems, networks, and sensitive data from any kind of unwanted attacks. Information security is the combination of computer security and communications security. Also known as INFOSEC.
Best practices of Cybersecurity
Information security mainly requires collaborative efforts throughout an information system, which includes:
- Application security
- Network security
- Disaster recovery/business continuity planning
- Operational security
- End-user education
What Are the Threats?
People who actually or potentially perform cyberattacks are classified into one or more of five categories:
- Criminals intend on the monetary gain from crimes such as theft or extortion.
- Spies intending on stealing classified or proprietary information used by the government or private entities.
- Nation-state developers who develop capabilities and undertake cyber attacks in support of a country’s strategic objectives.
- “Hacktivists” are the ones who perform cyber attacks for socially or politically motivated reasons.
Types of Cybersecurity Threats
It can be a hectic task to operate with new technologies, security trends, and threat intelligence. However, it is necessary to guard info and different assets from cyber threats that take several forms.
- Ransomware is a type of malware involving attackers locking the victim's computer system -- typically through coding -- and demanding a cost to decrypt and unlock them.
- Malware is any file or program used to harm a computer user in the form of worms, computer viruses, Trojan horses, and spyware.
- Social engineering is breaking security through human interaction. Here a person gets tricked into breaking their security measures stealing their sensitive information which is typically protected.
- Phishing is a sort of fraud where deceitful emails are sent that match emails from respectable sources. But those emails intend to steal sensitive information, like MasterCard or login data.
- Spam is uninvited bulk messages filtration or messages sent to multiple recipients to provoke them. The issues caused by spam area unit because of the mix of the uninvited and bulk aspects; the amount of unwanted messages spams electronic messaging systems and drowns out the messages that recipients do need.
- Spyware is a kind of software that gets installed in one’s system without their knowledge. It starts monitoring their online behaviors without knowing.
- Botnets are unit networks of systems which then infected by malware or controlled remotely by criminals. Used for gaining money or to launch attacks on websites or networks.
- Adware, or an advertising-supported software system, is a software system that displays unwanted advertisements on your system. ... Adware may have a lot of concise names for doubtless unwanted programs. It is not quite a virus and it should not be as malicious as loads of alternative problematic code floating around on the web.
Types of Cybersecurity Vulnerabilities
- Missing data encryption
- OS command injection
- SQL injection
- Buffer overflow
- Missing authentication for critical function
- Missing authorization
- Unrestricted upload of dangerous file types
- Providing untrusted entries in a security decision
- Cross-site scripting and forgery
- The download of codes without integrity checks
- Use of broken algorithms
- URL redirection to untrusted sites
- Path traversal
- Weak passwords
- Already virus-infected software
What Are the Impacts?
A successful attack can easily expose the confidentiality, integrity, and availability of a system and the information it possesses.
- Cyber theft or cyber espionage can lead to the filtration of financial proprietary or personal information for the attacker’s benefit which is mostly without the knowledge of the victim.
- Denial-of-service(DOS) attacks can slow or prevent legitimate users from accessing a system.
- Botnet malware gives an attacker command of a system which will then be used in cyberattacks on other systems.
- Attacks on industrial management systems may lead to the destruction or disruption of the instrumentality they possess, like generators, pumps, and centrifuges.
