Maintaining Network Security

Maintaining Network Security: For many companies, network security is necessary to achieve compliance for PCI, HIPPA and other regulatory requirements. Keeping your computer and wireless network secure is a good policy to protect your company’s critical data. Without proper network security, your network may be vulnerable to computer virus and malware attacks and unauthorized access by computer hackers. Here are five tips to help you maintain network security. Audit Network Regularly Performing a periodic network scan may identify unauthorized computers and other devices that may have connected to your network directly or via wireless access. Your properly configured network, firewall, routers and wireless access points will prevent unauthorized intruders, however, regular audits ensure compliance to your network security policies. Keep O/S Patches Up To Date Your network is as secure as its’ weakest link. Make sure all PCs are up to date with Operating System O/S security patches. This helps prevent computer viruses and malware from exploiting your operating system and entering your network. Keep Antivirus and Malware Definitions Current In addition to your O/S patches, confirm that your Antivirus and Malware definitions are up to date. This further protects your PC from exploits and helps maintain the security of your network. Establish Policy for Mobile and Wireless Devices Bring Your Own Device (BYOD) is a trend providing employees the benefits of using their mobile devices at home and in the workplace. Employers are relieved from the burden of having to purchase additional mobile devices, such as tablets and PCs. It is important to ensure these devices maintain the same security standards of company owned desktop and laptop computers....

Bring Your Own Device (BYOD)

Bring Your Own Device (BYOD) Bring your own device (BOYD) is a recent trend where employees use their personal mobile devices including: iPhones, iPads, tablets computers and smartphones to access company information including your network, email, files and critical business applications. This policy can make your employees more productive. BYOD may save you the expense of buying mobile devices for your employees. However, if not managed appropriately, BYOD may open up security risks in your data protection strategy. Due to their mobile nature, these mobile devices are susceptible to theft and loss. Also, mobile devices may infect your network with viruses and malware, if they are not properly maintained. Here are some tips to minimize your exposure to employees who BYOD: Require Passcode to Unlock Device Requiring a passcode will prevent unintended access to your network or application data in case a user’s mobile device is lost or stolen. Keep OS/apps Up To Date To avoid virus and malware attacks on your mobile devices, it is a good policy to keep the operating system up to date with the latest security patches. It is also a good idea to keep your applications up to date to avoid a network security breach. Don’t Allow “Jailbreaking” of Operating Systems Some employees may “jailbreak” their iPhones or iPads so they can install additional applications and extensions that may not be available through the Apple Store. Jailbreaking may expose security breaches on these devices creating a weak link in your data protection plan. Services for Tracking and Wiping Most mobile devices will automatically check in to their geo-location when they are turned on....

Is Your Network Safer Than The Titanic?

One hundred years ago the ship, called “unsinkable” had its hull breached by an iceberg and caused the death of over 1500 passengers. You may think your network is “invincible” like the Titanic, however, your network security policies may cause vulnerability putting your IT assets and critical data at risk. Here are several steps you can take to avoid compromising your network security: WiFi Access WiFi technology makes it easy for you to network your computers. Your WiFi signal may broadcast beyond the physical security of your office allowing uninvited visitors to access your network and compromise your network security and compliance policies. Make sure your WiFi network connections are password protected and securely encrypted. Also, consider turning off your WiFi during non business hours. By the way, wireless technology (the telegraph) saved the lives of hundreds of passengers on the Titanic. Thumb Drives and USB Drives Sharing data through thumb drives or USB drives may allow unintended computer viruses and malicious software, also known as malware, transfer from other non secure computers and enter the perimeter of your secure network. For this reason, some network administrators set strict IT policies that prevent thumb drives from being used on any office computer. There are plenty of secure services available for files sharing between computers (e.g. remote backup and remote control software). Ask your IT support professional about your policy for using USB drives and thumb drives and the impact they may have on your network security. Security Patches Operating System and Application Security patches are designed to keep your network secure. Your network security is as vulnerable as its’...

Why you should audit your network.

Do you know what’s connected to your network? If not, you should! Auditing your network and creating an inventory of your IT assets catalogs all devices connected to your network including PCs, laptops, printers, routers and switches. In some cases, assets discovered may even be unauthorized. By scanning and discovering all connected devices, your IT team can quickly perform a hardware and software audit. This helps ensure compliance with network policy, software licensing compliance, and compliance with industry regulatory requirements, such as, HIPPA. What’s more, having asset data cataloged, including hardware and software profiles, helps remote support technicians troubleshoot when things go wrong. What can you do with network audit data? Check your firewall’s security settings to make sure you are protected from the latest hacker attacks, worms, and viruses. Scan and remove spyware that is secretly stealing your company’s bandwidth, jeopardizing the speed of your computer system, and embezzling confidential information about you, your employees, and your business. Check your network’s backup system to ensure it is working properly and accurately backing up all of the critical files and information you never want to lose. Verify that you have the most up-to-date security patches installed properly; miss one critical update and you’re a “sitting duck.” Identify unstable PCs that may operate slowly. Search for all items meeting a criteria in summary and detail. For example, to determine how many machines use windows 7 with 4 megs of RAM to see if they are eligible for an O/S migration. Determine which devices may be out of software license compliance. Summarize warranty information for which devices are covered and which...

Happy Leap Day!

Every four years we all get something we all need in our busy lives, more time.  How we use that extra day may determine whether we become more productive or efficient.  Maybe that gift of an extra day will make us more relaxed.  This year February 29th falls on a workday, so here are a few ideas to consider. Decide to upgrade your network.  PCs, servers routers and other IT assets typically have a useful life of three to five years.  As technology advances at a rapid pace, your hardware and software assets become obsolete.  Your systems may become slow, sluggish and unreliable.  Obsolete hardware and software can contribute to loss of employee productivity or worse.  You may be a victim of malicious software attacks or malware because your old network is out of O/S patch compliance.  Like changing the battery in your smoke detector, consider upgrading that network at least every four years. Evaluate your line of business applications.  Has your business grown or changed? Does that accounting system continue to meet your needs?  Many businesses will outgrow their line of business applications within 5 years.  Use Leap Day to consider if your account software meets your current set of business rules.  If your policies and procedures have changed since the time you first implemented your account software, perhaps the system is holding you back.  Now is a good time to make sure your technology is in line with your business strategy. Update your technology roadmap. Now that you have an extra 24 hours, consider your future business and growth strategies.  Think through how those strategies may need...
