The Basics of Network Security

A network is two or more computers linked together in order to share data. From a security standpoint, the problem with networks is that unauthorized individuals might also be able to access that data. Network security is a term that encompasses your overall system for keeping your network as impenetrable as possible, be it hardware, software, or company policies.

Whether your network consists of two computers or two hundred computers, there are certain basic security measures you should have in place. Most of these measures aren’t complicated or expensive, and they don’t require any particular expertise in networking or computer security.

One of the most basic steps for securing your network is to have anti-virus software in place. Anti-virus software periodically sweeps your computer looking for known viruses. You can also choose to run a anti-virus test at any time. Once run, the software generates a report that lists the viruses detected. You are then able to select which, if any, of the viruses detected you want quarantined and removed. It’s more important that you keep your software up to date because new viruses are created and released every day.

Next, make sure you have a firewall in place. A firewall is like a gatekeeper. It’s a hardware/software combination that allows you to decide what goes in and out of your network. You determine the “trust level” to which your firewall is set. The trust level dictates which network connections will be automatically allowed and which will require specific permission. Firewalls come with a “default” setting which is unlikely to be stringent enough to meet your security needs. For optimum security, you should always manually set the trust settings to a higher degree of scrutiny.

Firewalls and anti-virus software are essential for another very important reason: they help protect your system from adware and spyware. Adware and spyware range from annoying to very dangerous. Adware slows down your system, and generates irritating pop-up ads that interfere with your work. Spyware is much more serious. It tracks your computer usage habits, and basically opens up a door to your network that allows hackers to penetrate your system without your knowing it.

Another simple measure is to regularly download patches for your software. Computer programs are tested for vulnerabilities and possible exploits before they are distributed to the public. However, it’s impossible to detect every single vulnerability in advance. As new exploits are discovered, companies “patch” their programs and software to prevent the exploitation of that vulnerability. Without these patches, the software and programs on your computer remain vulnerable.

Network security also depends on common sense. Weak passwords can cause big problems, but are easily avoided. Never use easy-to-guess passwords like your last name, phone number, or birth date. Always use a combination of letters and numbers. Your best bet is to avoid real words altogether and use a string of numbers and letters that stand for a saying or phrase you can easily remember.

Another common sense security measure is to delete suspicious-looking email. More importantly, never open or download an attachment from an email address you don’t recognize. Doing so could be inviting a virus right into your computer. When in doubt, follow this simple rule: delete without opening.

If your business, you should also put in place security policies to govern the behavior of authorized users. Even authorized users can pose a serious security risk, sometimes without realizing it. For instance, “I love to dance, I love to sing” could be “1L2D1L2S,” with the number 1 replacing the letter I.

Here are a few elements of a solid network security policy:

• Require your employees to change their passwords every 3 months.

• Do not allow employees to post their passwords on their desk or cubicle

• Immediately terminate a departing employee’s access to your network.

• Operate on the computer network equivalent to the “need to know” basis. Only allow an employee access to the programs and data that are essential to his or her job.

• Put all of your security guidelines down in writing, and post them where all of your employees can see them.

You want your network security policy to be tight, but not completely rigid. That is, if a given security measure is proving to be unworkable or a serious inconvenience, be willing to adjust. You can often achieve the same result through different means.

Last, but certainly not least, review your network security on a regular basis. A network that’s secure today may not be secure a few months down the road. Hackers are smart and are constantly developing ways to bypass security measures. Be smarter than the hackers by staying on the cutting edge of network security technology.

Introduction To Network Security

Network security is a critical aspect of most businesses today. Developing a plan that accommodates an existing IT infrastructure while incorporating enhanced network security along with improvements in daily operations and business resources is the best way to provide an affordable and efficient defense against threats.

The comprehensive protection of your business enterprise begins with an introduction to network security. It is essential to implement integrated defenses into your IT system in order to minimize the risks to your business. The damaging effects of exposure to dangerous threats both internally and externally can cripple your business, paralyzing it into a slow but steady demise.

Circumventing exposure to IT threats is more costly and time consuming than setting up a network security system to prevent such threats from entering your IT infrastructure.

At the basis of the potential for attack from new risks are many factors, not the least of which is the compliance to new regulatory demands that consistently leave network security exposed. Additionally, expanding the scope of your enterprise often escalates too quickly or so widely that the existing business IT structure becomes fragmented and open to security risks and threats.

Network security encompasses several different facets of any business enterprise. One of the primary goals of network security is to develop a flexible system that is strong and resilient. In turn, coupling this strength and flexibility with a consolidation of network resources creates a system that is fully protected throughout the organization. An introduction into network security should begin with a consolidated effort to improve and enhance the methods used to access data including improvements in monitoring and encrypting information. Prioritizing security risks will enable the ability to pinpoint the greatest risk in order to plug security holes and prevent infiltration from threats.

Another one of the primary objectives of network security is to safeguard customer databases. Protecting the network security of a business enterprise can lead to enhanced productivity. Less downtown experienced with equipment and personnel equates to more man hours and efficient output.

An effective network security strategy incorporates many aspects of a business. More importantly, it manages critical information relating to who has access to company content along with what these individuals are permitted to do. Additionally, a successful network security solution is capable of managing the identities of each entity that has access to business content including employees, customers, suppliers, and partners. More importantly, as companies go green and enable a remote workforce, network security becomes embroiled in more complicated issues that need to be addresses by trained professionals.

Identifying vulnerabilities and clearing the path to their protection is critical when shoring up the security of any company network. Business operations need to be designed to present the safest options all of the time, 24 hours a day, 7 days a week. All of these concerted efforts will lead to optimal efficiency within the business structure as well as improved network security throughout the IT infrastructure.

A Small Business Network Security Survey

Many of today’s small businesses use PCs and a server network to facilitate their operations. Important company information is stored in electronic format on these networks, and daily operations are dependent on the network being both available and secure. In many cases, these small businesses ignore or are unaware of the risks that could compromise the safety of the data. To better understand these issues, two hundred of these small businesses were interviewed about their network security. Companies ranged from those with ten employees or less, to those with over a hundred staff members.

Over half of the survey respondents believed that their network was adequately safe or very secure. A large number of respondents did admit that they doubted their defenses against an attack. This isn’t too surprising, as nearly all businesses have experienced some type of security threat in the last year, from lost computers or back-up takes, hacker attacks, viruses, or theft by employees.

The top three threats reported were:

1) Trojan horse or virus attacks
2) Stolen or lost computers, including data storage devices
3) Employee theft or hacker attack

Company defenses reported include:

1) Virus Protection
2) Firewall
3) Spyware Protection
4) Spam Filters

Recommendations:

Most companies reported that they lacked a smart password policy, automated patch management, and employee network use policies. Generally, many of these businesses don’t have full protection against an attack, and have not yet had to put their defenses to the test.

There isn’t one single fix to ensure secure continuity of operations on a network. However, we recommend a layered approach in managing these pressing security threats. This layered approach examines vulnerability in different areas including hardware, software, processes, and training. Every layer added another level of protection to the information environment.

1) Blocking network-based attacks
2) Blocking host-based attacks
3) Eliminating vulnerability
4) Supporting authorized users safely
5) Tools for maximizing effectiveness and minimizing losses

To assure the continuity of your business operations, regular testing of these security measures is required.

Level of Overall Security:

Over half the respondents stated that they thought their network was secure enough or better. 30% of the remainder thought their network was only somewhat secure, and over 10% confided that their network was not as secure as it should be.

These small businesses tend to believe that their network is relatively secure: 63% of businesses with less than ten employees and almost 75% of those with between eleven and twenty-five staff members. The larger companies were not as sure of their defenses, with over half of those with fifty to one hundred and 44% of those with over a hundred employees felt secure or secure enough. In the fifty-one to one hundred staff category, over 20% reported that the network was not as secure as should be. In general, the bigger the company, the larger the network – and the greater the number of security risks it must defend against.

Experienced Threats:

The respondents reported on security lapses or attacks that they’d experienced over the last year. The survey showed that Trojan horses or virus attacks are the most common threat to the network, with about half reporting experiences with these issues in that time. The larger companies reported at 40%, the lowest rate, which is indicative of better defenses. Over 60% of the smallest companies reported virus-based attacks.

Loss of company information from theft or loss of storage devices appeared to be a minor threat for smaller companies, but this risk increases with company size. Over 33% of the larger firms reported this sort of experience. Hacker attacks were most often experienced by firms with less than ten employees and those with over a hundred. It seems the smaller networks are more vulnerable, and the largest ones are high-profile, with a greater chance of becoming a target. Unfortunately, staff members can create a security risk themselves; about 10% of businesses reported that they had experienced unauthorized access or theft in the allotted time frame.

Devices and Procedures:

Good procedures, processes and systems can help defend against security threats. In the survey, respondents were asked which security methods were in use. Most reported that they had virus protection and firewalls. Around 25% lacked spam filters and spyware removal, leaving networks open to malware which ranges from dangerous to annoying. Under 50% have patch management or a smart password policy in place. This smart password system uses passwords with a mixture of normal and special characters which are frequently changed.

As compared to the largest companies surveyed, smaller businesses are less-often implementing network use policies for employees. Over 80% of the larger companies have defined guidelines for proper and improper network use. These guidelines attempt to lower the amount of network activity unrelated to the business, which result in increased security risk. Many of the respondents use wireless networks. Wireless networks are some of the most vulnerable access points if not well-secured. Only a few companies reported that they use all the top-priority security measures listed in the survey.

Testing:

No security device or feature can be known to provide real defense until it’s been tested. Anti-virus specifications could be out of date, a hole could exist within a firewall, or staff members could not be using the correct practices for a safe and secure network. About 25% of respondents indicated that either they couldn’t remember the last time they tested their security, or didn’t know that they ever had. This seems to indicate that while many have implemented security defenses, they can’t be assured that the expected protection is actually provided.

The very smallest companies least-often tested their security measures. About 10% of businesses had tested security, but not for over a year. As the threats change over time, dangerous lapses can occur without periodic testing. Around 33% of respondents reported that they’d tested their security measures within the last month. Validation of network security elements on a regular basis is important to system integrity in an overall continuity plan. It is unfortunate that usually a company only examines its level of exposure after a damaging event which negatively affects the business.
