Improving Your Company’s Network Security

February 10, 2015

As the technology and systems behind cyber-attacks are persistently evolving, it’s nearly impossible for any company to stay absolutely secure. However, there are a few important steps that must be taken to minimize the threats to your company’s network security. Here we have jotted down list of steps that a company should implement to strengthen security of its computer network.

  • Use Two Factor Authentication: Customary authentication methods involving a username and password are no longer effective from security point of view. Instead, you should prefer using a two factor validation combining the above two elements with some other confidential physical devices such as a smartphone, USB token, smart card etc. It can also incorporate biometric data like retina scan, fingerprint and voice recognition etc.
  • Have A Specified Security Policy: Whether you have a large or small company, there must be a comprehensive security policy explicitly stated to all the employees. This includes making sure that the software on their systems is up to date with a fully functional security cover. Latest anti-malware and antivirus software should be properly installed and inspected. Also, the staff should know whom to call if any system software needs configuring. Employees should also be educated about type of external devices that are prohibited on office computers.
  • Use Biometric Encryption And Passwords: If a company’s computer or laptop is stolen, there is a high possibility that someone can gain access to the confidential data, infect the network or access other computers. To prevent this, you can implement additional security features in the system such as encrypting the hard drive, facilitating a biometric password on start-up. You can also install BitLocker on your Windows computer to automatically encode the data saved on the hard drive or removable media.
  • Secure Access From External Servers: If any employee is accessing your server from a personal device, make sure that he has to pass through applicable verification measures. Introduce one time passwords (OTPs) or smart cards for the users to connect through the company’s VPN. If your company follows bring your own device (BYOD) policy, you must set up appropriate policies to ensure that it does not affect your network’s security.
  • Perform Regular Checks: It is very important that you review your security policy on a regular basis. Frequent system audits can help you measure the effectiveness of your company’s security operations against potential threats and attacks.

By devoting more attention to your company’s security practices, you will be in a better position to not just shield, but also correct the inconsistencies in your private network.

Secure Your Business Travel

January 27, 2015

Business travelers are always a prime target for the cyber criminals and spammers to gain access to their computers and confidential data stored therein. Thus, before you go on your next business trip, make sure that you follow these important security tips in order to keep your system safe from any sort of vulnerabilities.

  • Install Proper Security Updates And Patches: Before you leave for your journey, update the security software of the operating system and other applications for your computer. Also update the anti-virus software and if possible, enable it to update automatically. Although these processes may take a while, but it can prevent your system from security attacks by hackers.
  • Download Updates From Authorized Websites: If your computer suggests you to update certain software or applications, do not click on the ‘update’ button straightaway. This can be a malware to install spam software in your operating system. To avoid this, you should go to an authorized website and download the updates directly from there.
  • Always Use Virtual Private Network (VPN): Whenever you use the internet connection offered at public places such as hotels, airports and cafes, there is a higher possibility that your data can be intercepted and accessed unless it is properly encoded. This may include your username, password, documents and emails that you send etc. If your company provides VPN access, make sure you use it while traveling.
  • Beware Of Free Access Points: Unsecured Wi-Fi access points may seem to be tempting, but they may be a trap set by the hackers to spy on your private data. Malicious hotspots can also be used to redirect the users to spam websites that can infect the computer with viruses. However, if you need to connect to the internet, make sure that you opt for Wi-Fi services that require a password for authentication.
  • Encrypt Your Hard Drive: Your laptop may consist of some important business related data which may be at the target of cyber criminals. Make sure that your hard drive is properly encrypted and has a complete backup to keep all your information secure.
  • Avoid Using Public Computers: Computers in internet cafes and hotel business centers should never be trusted for any private communication or transaction. There may be a key logger installed to detect your username and passwords as you type.

It is also advisable that you change your laptop’s password once you have returned from the business trip.
