Computer networks and data is compromised because of persistent cybercriminals, careless users, and dissatisfied former/current employees. Network security encompasses policies & procedures, hardware, and software designed to protect the computer system from internal and external risks. Multiple protection layers thwart threats from bringing down the computer networks and even if they slip past security walls it stops them from stretching.
Common network system’s security threats are –
- Malicious programs like worms, Trojan horses, adware, botnets, viruses, malware, and spyware.
- Data theft
- Zero-day & zero-hour attacks
- DoS [Denial of Service] & DDoS [Distributed Denial of Service] attacks
- Hacker attacks
- Phishing attacks
What these threats seek to exploit?
- Weak passwords
- Unsecured wireless network
- Potentially unwanted applications
- Unsecured websites
- Lost devices
- Unpatched hardware & software
- Users with spiteful intent
Persistent advancement in computer & networking technology gets matched or exceeded by speedy and progressive hacking attacks. It is necessary to stay educated about cybersecurity vulnerability to fortify network defense to combat malicious attacks. Get to know the top network security basics to prevent downtime, reduce liabilities, protect your reputation, and adhere to government regulations.
Patches & updates need to be current
Administrators need not lax on applying the current versions of Adobe Flash, Adobe acrobat & reader, Oracle java, Microsoft office suite, and Microsoft internet explorer. Enable automatic update on Windows operating system.
Apply strong passwords
Passwords need to be kept out of direct sight rather than plastering on the computer screen. A strong password means a code hard to detect not only by humans but even by computers. It has to be of a minimum of 6 characters with a blend of lower- and upper-case letters, symbols, and numbers.
- Never use foreign words or proper nouns.
- Never use anything related like nickname, name, pets, or family member’s name.
- Never use street or phone numbers
- Choose a phrase, which seems important to you. Take the first or last letter and convert a couple into characters.
After every 2 months change your password. Never reuse the last 15 passwords. Train the user’s techniques on how they get tricked in divulging their passwords.
Secure your VPN
Open network connection gets exploited, especially when information is moving across the internet. So, data encryption and ID validity are very crucial to secure a VPN. A 2-step authentication process is better. Even use a firewall to separate the VPN network from the remaining network.
Clean inactive accounts
Inactive accounts are used under disguise, so as soon an employee gets laid or quits delete their accounts.
User access management
Never overlook consistent employee access management of critical data. Improper user-access privileges can pose great security threats. Therefore, when an employee posts changes ensure to notify the IT department to modify their access privileges according to their new position duties.
