Network security is a necessity for both home and office. There are several steps you can take to protect your network, systems and connections in order to avoid hacking, connection stealing and damage to your computers and documents. These 5 basic things that you need to know about network security can keep your network safe and secure.
Router Security
Your router can be configured to mask your various IP addresses, turn off broadcasting your wireless signal, set up wireless security passwords and networks and even firewall your network. Your router is essentially the key to your network security and when properly set up will protect all of your systems from damage and infiltration. This is the outer level of protection and can be considered the front door to your network.
Firewall Security
Each computer on your network should be protected by firewall security. A firewall can block out intruders, hide your documents and files and even catch and destroy viruses and spyware. Firewalls can be a hassle to computer users but are imperative for protecting the system and there are several unobtrusive firewall security programs that will run in the background and only call attention when there is a problem.
Cyber Security
There are several ways to maintain cyber security for your network. The first being firewalls and second generation firewalls for double protection. The next option is a virus and spyware program that will sweep your system and all files and downloads to protect from Trojans and other malware. You should also use your wits to make sure that you protect sensitive personal information from being distributed on the Internet and change passwords regularly to make sure that your network is impenetrable.
Unsecure Network Expenses
Your network is the hub of all computer activity and keeping it safe and sound is important for not only your information, work, and files but also for your wallet. Hackers and malware can cause serious damage to your computers and cost you repair fees and even cause you to have to replace systems. Even having a simple virus removed can cause a great deal of money when you have to take your computer to a service shop. There may be some costs incurred to make your network secure but it’s much less than the cost and damage if you get hacked or infected on a network level.
Professional Network Security
Network security is nothing to take lightly. There are so many levels of protection you can enable that there is no reason for your network to ever be vulnerable. If you are “technically ignorant” or generally have no clue as to how to go about setting up a secure network, contact a professional who can help you get your network security set up for your home or office. Don’t take the chance of your wireless signal being stolen by random strangers who can use that “in” to get into your computers and gather information or corrupt your systems.
Intrusion detection system as name implies is designed to block illegal access, unauthorized entry by third person or to deny leakage of any crucial information from your system. Firewall protection helps in decrypting random information that travels through different domains online. The best part of getting the protection of wireless intrusion detection system is how it creates a network of address translation that helps protecting the identity behind private address, which can be utilized by proxies to help corrupt information online. It is important to regulate installing firewall protection system for better traffic online. Since conventional users are vulnerable to threats on large number, any unseen damage done to your system can be dangerous.
Online threats illicitly enter premises of user’s PC which leads to more vulnerable crimes thus eventually cause network attacks or leaking of confidential data from corporate office, government office or other organizations. Since such cyber breaches lead to destruction it is certainly a must have for all. Firewall can be easily implemented in hardware and software or in combination.
Here are a few advantages that are offered for internet security:
Intrusion prevention software ensures that any illicit online user is not provided the required access to any private network when connected online. It is the major midpoint, which helps in keeping an eye over leaving or entering data on intranet. A dynamic protection ensures that unauthorized online users keep themselves away from reach to internet as each packet is examined and allowed to pass through specific secured criteria. Detection system forbids any illicit access over network and hinders entry of unauthorized communication.
It is among the most suitable ways to prevent your system from illicit entry of viruses, Trojans or malwares, which can induce damaging effects to user’s PC. Usually, a firewall operates by way of monitoring inbound traffic, as Window XP and Vista, for instance, fail to tackle multiple threats. In order to get complete firewall protection, one should go for two-way network firewall protection as it checks traffic for both inbound and outbound traffic for internet security threats.
The installed system is capable of analyzing the type of message and determines whether originator is authentic or not. Logically, the reason behind network security is protection against Trojans and key loggers as these threatening programs create nuisance for users. Failure to protect your computers may mean a failure to protect your business identity, which may ultimately hasten a person towards disaster.
The internet has been tightly embraced by many people today. Majority of work and activities are computer based, with all advanced technology connecting to the World Wide Web and possibly bringing network security close to risk. There are several threats that can bring threat to the computers of many, some more serious than others. Among the risky threats include viruses erasing the entire system, intruders breaking into the system and changing files, hackers that make use of the computer to attack others, or theft of credit card information and then unauthorized purchases.
Importance of firewall in network security
Cyber security includes protection of information by preventing, detecting, and responding to attacks. When anyone or anything can have control over system at any time, then it is more susceptible to being attacked. Unauthorized access to your computer and information can be prevented with firewall security.
Firewalls combat outside attackers by protecting your computer or network from malicious or irrelevant Internet traffic. These can be configured to ban data from certain locations while giving way to the relevant and necessary data. It is vital for the ones who bank on connections, whether cable or DSL modems.
Hardware (external) and software (internal) – are the two forms of firewall security.
Hardware – these are also known as network firewalls and placed between the computer or network and the cable or DSL modem. Routers offered by many vendors and some Internet service providers (ISPs), incorporates firewall features. This form of firewall is desired for shielding multiple computers but along with it, is excellent protection to a single computer. If there is single system behind the firewall, or you are sure that other systems lined on the network are up to date on patches and protected from viruses, worms, or other malicious code, then there is no need of extra protection of a software firewall.
Software – No matter if an operating system includes a built-in firewall; you should always consider adding another layer of shield. If there is no built–in firewall, you can obtain it from a cyber Security Company. There can be risks of downloading software from the Internet onto an unprotected computer. In case you are downloading to your computer, then ensure the website is reputable and secure.
Besides, users should employ good habits, when it comes to network security. It will dramatically bring down the possibility that information on a computer can be corrupted.

5. In order to get complete firewall protection, one should go for two way network firewall protection as it checks traffic for both inbound and outbound traffic for internet security threats.
6. Two ways firewall protection is necessary; it keeps check on both inbound and outbound traffic, keeping it safe for the user.
7. It functions in the most simplified way as method of communication in the network by passing small packets from the originator. An installed system is capable of analyzing the type of message and determines whether the originator is authentic or not.
Logically, the reason behind network security is protection against Trojans and key loggers as these threatening programs create nuisance for users. Failure to protect your computers may mean failure to protect your business identity, which may ultimately lead to trouble in the future.
Worried about intruders attacking your network enterprise? Do not surround yourself with clouds of tensions, but rather seek for intrusion detection software (IDS). Electronic attacks can hamper the operation of Information systems and networks. IDS is a must have tool especially if you are planning for serious in depth computer security. Antivirus scanners point known worms, Trojan horses and viruses, and firewalls halt port intruders. However, what about activities taking place in the network packets? The IDS is capable of detecting whether port 80 traffic is a web request or an Instant messaging file transfer. On the contrary, firewalls and scanners are not capable of holding buffer overflow attack or cannot make out the latest SQL injection attack. Advanced high end IDS is capable of dropping the packet before harm is disseminated. It is also designed to alter or modify the security parameter ruling out the possibilities that may harm the network.
Intrusion detection system can be categorized in the following ways:
Misuse detection vs. anomaly detection
In misuse detection, the IDS scrutinize the incorporated information and then make comparison with the large databases of attack signatures. Basically, it searches for a specific attack that already took place. Detection software of a virus detection system checks the database of attack signatures and compares packets against them. In anomaly detection, the system administrator creates the baseline, or normal, networks traffic load, protocol, and typical packet size. The anomaly detector checks the network segments to compare their state to the normal baseline and search for the anomalies.
Network-based vs. Host-based systems
Network-based system, in this Intrusion detection system investigates the individual packets passing through the network. All malicious packets which a firewall is unable to detect are filtered through it and ensure network security. A host-based system eyes activities on the individual’s computer or host.
Passive system vs. reactive system
In a passive system, network security is done by checking the potential security breach, logging the information and sending out alerts. In a reactive system, suspicious activities are detected by logging off a user or by reprogramming the firewall and stops network traffic from the suspected source.
Firewall security and IDS are related to the cyber security. The difference lies in the methods of providing security. The firewall searches for intrusion so they can be stopped from happening and maintains the privacy by limiting the access between two networks and avoiding having to warn an attack from inside the network. On the contrary, the intrusion detection software reviews the suspect after the spread of warning.
Defending your system against spyware and malware programs have become a major prerequisite for users worldwide. If you are really looking for a better backup for your PC, installing a firewall security is all you’ll need. The firewall security is a form of computer security, which blocks unauthorized access to your computer or local Area Network (LAN) that you are working in. Installing a firewall protection system is all one will require as it works as a great defense mechanism against spywares that your system may encounter every now and then. It works precisely by transferring the required traffic between computer networks.
Each of the networks in cyber security is provided with a certain trust level, which is set by the user within the firewall itself. For example, internet is usually considered as a zone whereas internet network would be given higher priority and trust level by firewall programs. It also provides security for various other security threats and vulnerabilities to your PC as well. If you want your firewall protection to be worthwhile, ensure its configuration is done properly and wisely to avoid any future mishaps. In order to get complete network protection, use standard security practice which will allow you to have access to network connections.
In order to derive the complete benefits of network security program, one requires having detailed information and precise understanding of network application in order to use it in organizations on a regular basis. Since most online users don’t understand the set rule, they apply a default rule set. In that case all the traffic is allowed to have access to your computer unless it has been specifically blocked by the user. This criterion is not healthy for your system as your network connections and security can be compromised. Connecting a dynamic protection system is all you need to keep it safe at your own end.
Ensuring security by installing a firewall is not enough, as you will also need the protection of virus scanner, anti-spyware and anti- adware software. Keep all the essential softwares updated and avoid intrusions happen to your PC.
The basic role of firewall is to monitor and standardize the required traffic between networks with appropriate security and trust level. A firewall blocks the security attacks to your computer, keeps hackers away from your system, hides system addresses and creates a safe and secure environment for your business or personal system.

Internet security is the basic necessity of any server and helps in detecting unauthenticated elements that try to penetrate your accounts, emails or online world. Important tips essential for every Wi-Fi user wanting to improve network security on a wireless connection are mentioned below:
Change the default administrator username and password
Every home Wi-Fi network has an access point or router which controls the setting. Manufacturers provide some web pages that allow the owners to enter into the user’s network, address and account information. These web tools can be protected by the login screen to allow only the rightful owner to work with it. By changing its settings, you can easily prohibit hackers from misusing your control panel to extract information.
Get WPA/WEP encryption
Encryption is a technology that scrambles the messages sent over wireless networks and makes them temporarily unreadable. Pick the strongest form of encryption that is compatible with your wireless network. Since all Wi-Fi devices on your network must share identical encryption, you need to find the “lowest common denominator” setting.
Avoid auto connect to open Wi-Fi networks
When you connect to an open Wi-Fi network, your computer is exposed to security risks. Although most computers have an available setting that allows these connections to be processed automatically without bothering the user, the user should disable this setting to prevent unauthorized connection to his network.
Use firewalls for every computer and router
The latest network routers have built-in firewall capabilities with the option of disabling them. These firewalls are very essential for wireless network security since the firewalls installed can provide you with regular alerts and notifications in case of any unidentified software heading your way. It also scans incoming and outgoing emails to check for viruses, spam and hacking attempts. Therefore, for extra protection, consider installing and running personal firewall software on each computer connected to the router.
By following these important tips, you can prevent your computer and router from being hijacked by hackers.
