Top 5 Most Common Security Issues and How to Fix Them

Viruses and Worms Viruses are the most common threats everyday internet users face, with 10.5 billion malware attacks reported between 2015 and 2019. Approximately 33% of computers are affected by malware, most being viruses. A computer virus attack on your network can bring about irreparable damage to your system.

The most common network security threats

• Trojan horse.
• Adware and spyware.
• Computer worm.
• DOS and DDOS attack.
• Phishing.
• Rootkit.
• SQL Injection attack.
• MIM attacks.

1. Code Injection. Hackers are sometimes able to exploit vulnerabilities in applications to insert malicious code.
2. Data Breach. The cost of data breaches is well documented.
3. Malware Infection.
4. Distributed Denial of Service Attack.
5. Malicious Insiders.

Viruses, worms, Trojans, and spam are ubiquitous, but they are just the tip of the iceberg. Other common information security threats include privilege escalation, spyware, adware, rootkits, botnets, and logic bombs.

1. Enable encryption on your access point.
2. Set the router access password.
3. Disable MAC Address filtering on your Access Point or router.
4. Don’t disable the ‘SSID Broadcast’.
5. Disable remote login.
6. Disable wireless administrating.
7. Update your software regularly.
8. Remove unnecessary services and software.

What are the three general sources of security threats? A security threat is a challenge to the integrity of information systems that arises from one of three sources: human errors and mistakes, computer crime, and natural events and disasters.

Types of Computer Security Threats and How to Avoid Them

• Computer Viruses. Perhaps the most well-known computer security threat, a computer virus is a program written to alter the way a computer operates, without the permission or knowledge of the user.
• Spyware Threats.
• Hackers and Predators.
• Phishing.

What Are Techniques to Prevent Unauthorized Computer Access and Use?

1. Use strong passwords.
2. Use antivirus software.
3. Keep software up to date.
4. Verify your software security.
5. Build personal firewall.
6. Back up early and often.
7. Protect against power surges and loss.
8. Be careful while surfing on the Internet.

Wi-Fi technology evolves with time, and WPA2 has been considered the most secure method of protecting your Wi-Fi connection since the mid-2000s. While there are other methods of Wi-Fi encryption, WPA2 is recommended by everyone from Cisco to Apple for wireless security.

Wireless mesh networks eliminate the cost of installing wires in complicated areas, they are extremely adaptable and expandable too as wireless mesh nodes can simply be removed or added to the network, and more.

There are still some security vulnerabilities with WPA2, but it is still considered one of the most secure wireless network protocols available for personal and business use. While like WPA, it also offers users personal and enterprise/business modes. WPA2 also has several security improvements.

WPA2

WEP is a notoriously weak security standard: the password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools. WEP is an old IEEE 802.11 standard from 1997, which was superseded in 2003 by WPA, or Wi-Fi Protected Access.

You’ll instead see a “Weak security” message that says “WEP is not considered secure”. That’s because WEP is an older encryption scheme that can be very easily compromised. You shouldn’t be using WEP, if possible. Modern WPA2 security with AES encryption is ideal.

WAP (Wireless Application Protocol) is a specification for a set of communication protocols to standardize the way that wireless devices can be used for Internet access.
