Modern business networks are comprised of numerous remote access connections from employees and outsourcing firms. Most of the time, the inherent security risks that arise from these connections that are not part of the network are left unnoticed. Continuous improvements have been made to enhance security in the current network infrastructure. Paying particular attention to the users who access the network from outside and monitoring access ends points is crucial for businesses to protect your digital asset.
Installing the right software to meet the particular requirements that you have for the IT infrastructure is vital to have the highest security protection possible. Many businesses install “off the shelf” security software and believe that they are protected. But that’s not true due to the nature of today’s cyber-security threats. They are diverse in nature which includes the standard malware, spyware, spam, trojans, worms, and the occasional possibility that a hacker has targeted your servers.The right security solution for your company will eliminate almost all threats for your system. Too often, when there is only a software package installed the network administrator spends much of their time on the perimeter of the network defending the integrity of their network by manually fighting off threats and manually patching the security vulnerability.
The cost of paying network administrators to protect the integrity of your network can be a costly option – far more than investing in the appropriate security solution that your network needs. Network administrators are also faced with a myriad of responsibilities that need their attention. Part of their job is to make your business perform more efficiently. They must be focused on this, but they must manually protect networks all the time.
Another threat that must be taken into consideration is the risk occurring from within the perimeter, in the sense of an employee. Information that is confidential and proprietary is often stolen by employees on the payroll. An effective security solution for your network must guard against these kinds of attacks also. Network administrators play a crucial duty in this field in establishing security policies and then strictly enforcing them.
A great way to give your network the protection it needs from the different security threats is to employ a multi-layered security method. Layered security is a custom method to meet your network’s unique requirements utilizing both hardware and software solutions. Once both software and hardware are in sync to protect your business, they are in a position to immediately update their capabilities in order to take care of the latest in security threats.
Security software can be programmed to update multiple times a time if required hardware updates generally consist of firmware upgrades and an update wizard similar to one found within the software application.
All-in-one Security Suites A multi-pronged plan of attack should be employed to tackle the multiple security threats that exist in today’s corporate networks. Many times, the source of these threats overlap with Trojans appearing in spam or spyware hidden within software installations. For a successful fight against these threats, one must make use of firewalls, anti-spyware, spam protection, and malware https://dll-files.org/.
Recently an increasing trend in the world of software has been to merge the previously distinct security software to create a comprehensive security suite. Security programs that are standard on corporate networks are being integrated into security suites focusing on a common objective. Security suites include antivirus, antispyware, antispam and firewall security all integrated into one program. Finding the top stand-alone security suites in each risk area is an option, but not required.
The all-in-one security suite will help companies save money through the form of lower costs for purchasing software and time with the ease in integrating management of various threat sources.
Trusted Platform Module (TPM)A TPM is a standard developed by the Trusted Computing Group defining hardware specifications that create encryption keys. TPM chips not only guard against attempts to hack into the system and software attacks but also physical theft of the device containing the chip. TPM chips work as an additional layer of authentication, enhancing the security process.
Authentication describes the entire process involved in determining whether an individual who has access to the corporate network is, in fact, who that is claiming to be. Authentication is most often obtained through the use passwords, however, other techniques involve biometrics that are unique to a particular user, through identifying an individual characteristic that no one else has such as a fingerprint or the characteristics of the eye cornea.
Nowadays, TPM chips are often included in the standard laptop and desktop motherboards. Intel began integrating TPM chips inside its motherboards around 2003, like other motherboard manufacturers. The fact that a motherboard is equipped with this chip will be included within the specifications of that motherboard.
These chips can encrypt data at the local level, thereby providing greater security when you are in remote locations like the WiFi hotspot brimming with innocent looking computer-users who may be bored hackers with malicious intent. The Microsoft Ultimate as well as Enterprise Versions of Vista Operating System utilize this technology inside the BitLocker drive Encryption feature.
While Vista does support TPM technology The chips aren’t dependent on any particular platform to function.
TPM has the same functionality on Linux as it does on TPM’s Windows operating system. There are also specifications from the Trusted Computing Group for mobile devices, like PDAs and cell phones.
To benefit from TPM for enhanced security, users of networks only require downloading the security policy to their computer’s desktop and use a wizard to set up the system that will generate a set encryption keys for that computer. Following these simple steps significantly improves security for the distant computer.
Admission based on User Identity Identity verification for a user is contingent upon completing the authentication process. As mentioned previously, authentication for users can involve much more than just a name of the user and a password. Alongside the growing biometrics technology for user authentication, smart cards and security tokens are an additional method that can improve the user’s name and password authentication process.
The use of security tokens, also known as smart cards, creates a need for hardware to the authentication process. This creates a two-tier security necessity, one being of which is a secret password. The other is a requirement for hardware that your secure device must recognize prior to granting access.
Smart cards and tokens function similarly however they have a distinct appearance. Tokens take on the appearance like a flash drive, and connection through a USB port, while smart cards require special equipment, such as a smart card reader, that connects to a laptop or desktop computer. Smart cards often take on the appearance of a identification badge, and could also contain an image of the employee.
However , authentication is checked, once this happens the user is granted access to the network via the secure virtual network (VLAN) link. A VLAN establishes connections with the remote user like that person was a part of the network’s internal one and allows for all VLAN users to be grouped together within separate security policies.
Remote users connected to VLANs should be granted access to necessary network resources and how those resources can be copied or altered should be watched carefully.
Specifications formulated in the Institute of Electrical and Electronics Engineers (IEEE) have led to what is now known as”secure” VLAN (S-VLAN) design. Also known as tag-based vLAN, the standard is referred to as 802.1q. It enhances VLAN security by the addition of an additional tag to media access control (MAC) addresses that can identify the network adapter hardware in a network. This method will prevent non-identified MAC addresses from accessing networks.
Network Segmentation This idea, which works together along with VLAN connections, determines the resources an individual user is able to access remotely using policy enforcement points (PEPs) to ensure the security policy is enforced across the network segments. Additionally the VLAN is also known as S-VLAN, can be treated as a distinct segment, with specific PEP requirements.
PEP integrates with the user’s authentication to enforce a security policy of the network. Anyone who connects to the network need to be assured with the PEP that they are in compliance with the security policies contained within the PEP. The PEP determines what network resources an individual user has access to, and how these resources can be modified.
The PEP for VLAN connections must be enhanced from what the same user can do with the resources within. This can be achieved through the network segmentation process by simply defining the VLAN connections as separate segments and enforcing an identical security policy for the segment. The policy that is defined in this manner can also define the internal network segments the client has the ability to access from an off-site location.
Keeping VLAN connections as a distinct segment also helps to isolate security breaches to that segment in the event that one should occur. This stops this security issue from spreading throughout the entire corporate network. Further enhancing security of the network The VLAN segment can be managed with its own virtualized environments which isolates all remote connections in an organization’s network.
Centralized Security Policy Management Technology software and hardware that tackle the different facets of security risks create various software platforms which all need to be managed separately. If it is done wrong, this can be a huge undertaking to administer a network, and could increase the cost of staffing because of the greater time needed to manage the technologies (whether they’re hardware or software).
Integrated security software suites help centralize the security policy by integrating all security risk attacks into one application, thus requiring only one management console for administrative purposes.
Depending on the type of business you’re operating, a security policy should be adopted across the company, and should be inclusive of the whole network. Administrators and managers can create the security policies in different ways however, the overriding meaning of the policy should be maintained so that it’s consistent across the corporate network. This will ensure that there aren’t additional security measures that go against the centralized policy , while also limiting what the policy was formulated to apply.
Not only does a centralized security policy become easier to control, but it also reduces strain on resources of the network. Multiple security policy definitions by various applications that focus on a single security risk can in turn consume more bandwidth than an centralized security policy contained within an entire security system. With all the threats emerging from the Web it is essential to have a simple management and application is vital to maintain any security policy.
Frequently asked Questions:
- I am confident in my employees. Why should I enhance security of my network?
Even the most reliable employees may be at possibility of a security breach. It is essential that employees adhere to established company security procedures. The improvement in security can guard against employees who have stopped working and the occasional disgruntled employee seeking to harm the network.
- Do these new technologies actually create an environment that is secure enough that allows remote access?
Yes they are. These enhancements not only greatly improve the security of a VLAN connection however they also employ well-known standards that are frequently integrated into standard hardware and software. The technology is there, your business just needs to begin using the technology.
- My company is comfortable using separate software, that lets each application focus on a particular security threat. What are the benefits of an all-in-one security solution?
A lot of the well-known software programs used by businesses have expanded their scope to detect all security threats. This includes both solutions from hardware and software makers. Many of these companies realized the need to consolidate their security early on and purchased smaller software firms to gain the experience their firm was lacking. A security suite at the application level, can make managing much simpler and your IT personnel will thank you for it.
- Do I require an additional requirement for hardware to the authentication process?
The requirement for the use of security tokens or smart card should be considered for employees accessing the network of the company via a remote site. Particularly, if the employee has access to confidential company data while on the road using a flash drive, a secured token can stop a burglar from accessing the sensitive information on a stolen laptop.
- With all this concern about WiFi hotspots, is it right that employees should be prohibited from using these hotspots to connect to the company network?
WiFi hotspots have been popping up across the country and offer the most convenient method for your remote employees to access the Internet. Unfortunately, hotspots can also be full of bored insecure hackers with nothing better to do than discover a way to intercept employees’ communications at the table next to them. However, employees on the road should stay clear of hotspots. That would severely limit them from connecting to the network at all. With technology like S-VLAN or secure authentication in place, companies can adopt technologies to reduce threats both now and in the future.
Implementing the latest security tools is a top importance for IT Management. In today’s world of networks with numerous users accessing your digital assets remotely It is crucial to ensure the security of your network in order during the planning phase of the integration process.
It is important to be observed that many large organizations are operating on multiple operating systems (Windows or Mac OS, etc) and for a lot of them, all-in-one security suites face certain challenges when operating in a mixed system environment.
This is why I advise that you consider having layered security (both software and hardware) and don’t rely solely on software to secure those digital files. With the advancement of technology, also do the chances for security incidents.
As these security threats become more sophisticated Hardware and software developers will continue to innovate and it’s crucial that businesses keep up , and use these techniques.
