Internet Security or Cyber Security is defined as set of rules, regulations and computing security measures established against attacks over the Internet.
It is important to note that Internet Security is also known as Cyber Security. It is a branch of Computer Security specifically related to the use of Internet, browser security, network security, internet applications, operating system and the World Wide Web.
The use of the Internet has increased recently and because of the ever-increasing needs, threats to computer systems are also increasing which has prompted measures known as Internet Security or Cyber Security.
Some of the features of Internet/Cyber Security include:
1. Firewalls: This can be hardware or software devices to prevent sensitive information from being uncovered and stolen from networks and also prevent dangerous information — such as malicious code — from being planted on networks. Firewalls apply a specific set of rules to all information coming in or going out of networks to determine whether it's dangerous or benign.
2. Browser Security: Browsers can have security flaws, which allow hackers and cyber-criminals to attack computers and networks. You must choose a secure browser and keep it updated with new security patches for the developer releases. In other to have a safe and cookie-free browser, it is necessary to always keep the browser you are using up to date, clear every cookie after use, stop allowing pop-ups to add cookies to your computer.
3. Email Security: A solid email security strategy includes both anti-malware applications and good practice by users, such as not sending sensitive information via unsecured email and not opening suspicious messages. Electronic mail (email) offers many potential vulnerabilities. It's often used to send sensitive information, which then becomes vulnerable to theft, and is also used to distribute malware.
4. Denial-Of-Service Security: Denial of Service (DoS) attacks are performed against computer resources such as websites. The aim of a DoS attack is to make a resource unavailable to users. Methods for protecting against such attacks include firewalls and systems such as "clean pipes," in which website traffic is routed through a proxy server that drops bad traffic, allowing only genuine requests. DoS protection can be provided by third-party services such as CloudFlare, Incapsula, Oracle etc.
5. Social Engineering Security: The strongest firewall and high-security anti-virus suite won't protect your system if you give away sensitive information such as passwords or security questions. It uses tricks to make you hand over information to criminals. An example is phishing, in which an email appears to come from a reputable organization such as a bank, tricking the recipient into entering their personal details. The phisher can then collect and use them to log in to the victim's account. Extra caution is needed in entering vital information on internet forms and interfaces.
6. Operating System Updates: Operating systems can easily be attacked if they lack security updates and patches from manufacturers. Your computer's operating system needs to be regularly updated with patch releases from manufacturers in order to keep it secure.
7. Auto-Save Options Security: It is also advisable not to use auto-save options on your browser especially when you are using a general or public computer.
8. Anti-Virus: Antivirus software also known as anti-malware is a computer software program used to prevent, detect, and remove malwares from your computing devices.
The Key Internet attacks on individuals and organizations are:
1. Identity Theft,
2. Cookies Spying,
4. Device Intrusion,
5. Domain Spoofing,
6. Email Spoofing,
7. The spread of Viruses,
8. The spread of Malwares,
9. Social Engineering,
10. Poison Filters
11. Spamming etc.
Identity theft: This is an attack that is targeted to steal valuable user's information. When the Identity of customers in an organisation is lost or stolen, it leads to loss of reputation of that organization. Identity theft is one of the most popular methods used by hackers in recent years to steal valuable information such as:
5. Credit Cards etc.
Cookies Spying: This is known as stealing cookies information or data from users. Cookies are files that hold a small amount of data, particularly specific to a website and it stores username, password, and session which are temporary and can be deleted at any time. We have these types: Session, Permanent and Third-party cookies.
Phishing: This is the attempt to obtain sensitive information such as credit card details by disguising oneself as a trustworthy entity or impersonating an organization in electronic communication. One of the ways in which phishing can be detected is fake URL, bad grammar, suspicious links in email, poor spelling, etc.
Spamming: is sending unsolicited emails to bulk email accounts and in general, contains advertising about counterfeit or zero products or services. The real problem is that they can contain malware that can damage or extract user's data. Some of the techniques used by spammers are domain spoofing, poising filter, junk tags, etc.
The main aim and objectives of Internet Security are to establish rules and measures in order to prevent or reduce these internet fraud and thefts.
1. It educates on how to protect our sensitive data.
2. It helps to know measures to take to secure our computers.
3. It helps to prevent attacks on your personal computers and devices.
4. It helps to know how viruses and Trojans affect our computing devices.
5. It helps to learn about social media security.
6. It creates job opportunities.
7. It can serve as a source of self-employment.
8. It prevents users from unauthorized access to our networks.
