The Importance of Network Security to Prevent Hackers
Dec 8th
A network is a system that allows a number of computers to be interconnected. In other words, we can also say that a network is a mode of access between distant places for the data to flow easily to and from one computer to another. It helps people stay connected around the world.
During the process of sending and receiving data there are risks of files being hacked. Therefore, in order to protect such attempts by hackers, network security is essential. The main purpose of setting up network security is to avoid the misuse or unauthorized access to the network or its component parts. Networks are large and small in size but for network security, size is not an issue. So for a network to be protected against inevitable losses, it is important to secure it with strict policies, which can only be done through network security.
Why is Network Security Important?
Network security is very important to protect confidential documents against misuse of the system. There are a number of drawbacks that can arise if network security is not launched properly, some of which include:
1. Violation of Confidentiality: Every business has some information that is required to be kept confidential from other competitors and even from their own employees.
2. Damaging Data: Data is an important and valuable asset for any company or sole proprietor as it is the core of what your information is based on. Therefore backup scripts are also set for the data to be stored on other available media. If the data is damaged by any means, then the victim will face severe loss and can cripple the business severely.
Why Should My Business Focus On Network Security
Dec 6th
The modern business can no longer get by with an unprotected network. Fortunately businesses and homeowners are now seeking professional network security.
Many small businesses assume that employing a hardware router or software firewall makes their network secure. It is more secure than having nothing between your computer and potential threats. However, it is not enough to prevent the serious threats to the business or homeowner’s private information.
The Four Components of Network Access Control (NAC)
Professional network access control focuses on four elements. These are authentication, enforcement, endpoint security, and management. Do you know how strong these components are in your business’ network?
The best decision that a business can make for their network is to seek consultation and appraisal of their network security. Network security firms often offer this initial evaluation at no charge.
Authentication
The core element of a secure network is a comprehensive authentication protocol. To a large degree, firewalls handle these authentication needs but they often have two shortcomings, they cannot completely prevent the snooping of unencrypted transmissions and they assume that all threats originate externally.
Enforcement
Enforcement is the next tier beyond authentication. Basic networking security assumes that an authenticated client never becomes a security threat. Continuous enforcement ensures that they never do.
Endpoint Security
Endpoint security is a NAC strategy focused on keeping people on the network rather than keeping them off. This tier empowers continuous enforcement through a lifecycle approach. This means stages of assessment, monitoring, remediation, and then enforcement integration, wrapped up in a management structure and global policy definition.
Network Management
The management tier is the final and perhaps most critical level of network security. This is where the security firm ties the pieces of network security together with the needs of the business. This includes interfacing departments within the business.
Network security audit and monitoring
Dec 5th
Network security requires constant care and monitoring. With Nsauditor Network Security Auditor, Systems Administrators are able to gather a wide range of information from all the computers in the network without installing server-side applications on these computers. It is a multi-purpose tool designed to scan networks and hosts for vulnerabilities, and to provide security alerts.
Nsauditor Network Security Auditor significantly reduces the total cost of network management in enterprise environments by enabling IT personnel to audit and monitor remote network computers for possible vulnerabilities. The software network auditor module checks network for all potential methods that a hacker might use to attack it, discovers network services and checks them for vulnerabilities.
Nsauditor is a complete networking utilities package ( more than 45 network tools in one ) that includes a wide range of tools for network auditing, scanning and monitoring. The product contains a built-in database of known network security vulnerabilities, which allows you to select the items for scanning and add custom entries. Nsauditor can discover NetBios names, audit MS SQL servers, scan for common Adware traces, discover services, devices, processes, installed applications, disks, shared resources, hardware resources, users, local groups and much more. Nsauditor Network Security Auditor has a centralized network monitoring interface, which allows to monitor the entire network from a single computer.
Nsauditor Network Monitoring module shows you detailed listings of all TCP and UDP endpoints on your system, including the owning process name, remote address and state of TCP connections, country of origin and service name/description. When you start Nsauditor it will enumerate all active TCP and UDP endpoints, resolving all IP addresses to their domain name versions. You can close established TCP/IP connections by right-clicking on a connection and/or request IP address whois information or trace route.
Nsauditor “Adware Scanner” tool scans network computers for common Adware traces. Adware Scanner searches system registry and gives you a quick look at the Adware, malware and spyware installed on your computer or in the range of network computers. Using colored icons Adware Scanner shows harmful objects.
Removable devices create additional challenges for network security protection. Portable storage devices can be used both to download confidential data as well as to introduce a virus into the company network. Nsauditor Network Security Auditor “Removable Explorer” tool gives IT staff more control over unauthorized and dangerous removable devices ( USB device, CD-Rom and DVD ) by allowing them to scan the network for all removable devices that are connected to any one of the network computers. Removable Explorer displays remote network computer USB devices, CD-Rom, DVD drive or other removable storage device information and state, drive type, first and last plug in time, serial number, revision, device name, device vendor and more.
Nsauditor performs event log based intrusion detection, monitors the security event logs of Windows 2000/XP/2003 servers or workstations and notifies of the possible intrusions/attacks by using E-mail, Net Send, Speech Recognition method or by playing user selected voice file.
In summary, Nsauditor Network Security Auditor is a very complete network tools package for a surprisingly low price.

A Small Business Network Security Survey
Dec 3rd
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.
