The vast network of cyberspace presents or, can host major threats to the protection of computers, LAN and Wide area networks, and wireless networks. Trained computer networking specialists who're experts in cyber protection are required to secure systems and computer systems for successful information storage and recovery. As importantly, they're required to secure the integrity and privacy of corporate and personal identities. Most people finish at least a bachelor's degree prior to working in the cyber protection field. Hackers pose particular threats to computer network security. These technologies and networking experts use their privileged information to give themselves access to computer programs, without permission.
Much info should be kept private, and serious harm can ensue if this info falls into the hands of hackers. Among the best risks to company computer and computer users who're working on unsecured networks is id theft. A cyber thief could use a personal or business address, fiscal and credit card information, or a private social protection number to steal money from individuals or corporate accounts. Cyber security professionals who're adept at designing secure, hack proof info systems and networks are necessary to win the struggle against id theft.
The back door
One of the points that a hacker can gain access to your private network are not via your computer, because you properly have an up to date antivirus software and a firewall, to keep out unwanted guests on your computer, and with a modern phone you probably also have a security system on that phone. so you would believe that your identity and information are secure but they are not.
A good hacker might use your smart tv, or other smart devices such as smart lights to gain access i even saw a hacker go through several devices before finding one that had a open access to the computer, because it was a tv that were used as a monitor for the computer when showing presentations and therefore had a direct connection to the computer.
How to make the backdoor harder to get through
Here are some steps to protect your home network and the gadgets connected to it.
Secure the wireless network. The old Wired Equivalent Privacy (WEP) protocol is still widely used, but it is weak and easily compromised. Make sure the home wireless network is instead protected by the Wi-Fi Protected Access II (WPA2) protocol and a strong, complex password.
Give your Wi-Fi network an obscure name, or SSID, that doesn't give attackers personal information they can use in social-engineering attempts. For instance, don't call it "[Your Name] House." Instead, call it something random, such as "FBI Surveillance Van."
Disable guest network access entirely, and to be strict about who or what can get on the network.
Create two different Wi-Fi networks if your router can handle multiple SSIDs. Trey Ford, global security strategist at security company Rapid7, suggests one network for computers, tablets and smartphones used for online banking, shopping and general Web activity; another network can be for smart devices.
Good password management is essential. Neither network equipment (such as routers and switches) nor newfangled gadgets (such as smart TVs) should use default factory-set administrator passwords. Change each admin password to something suitably strong and complex, and regularly change them going forward. When possible, usernames should be also changed to make it even harder for attackers to brute-force their way in.

Firewall the network, either with a stand-alone appliance or software that ships with the router, to restrict incoming connections.
"Every home with an Internet connection should have [a firewall]," Martincavage said.
Most networked IoT devices include information about the ports, network protocols and IP addresses used in the owner's guide or the support website. Set the firewall to allow traffic on those specific ports and no others. Port restrictions will cut down on opportunistic network-probing attempts.
"If [devices] require a wide-open access to, or from, the Internet, beware!" Martincavage said.
Install a unified threat management appliance (UTM) if you have a highly-connected home, Martincavage suggested. It will handle intrusion detection and prevention, manage the Internet gateway and provide network antivirus protection.
A good UTM small-business models start at about $300 will have signatures and countermeasures to detect and stop the more common network entry points that attackers will use, Martincavage said.
