How to Improve Network Security
Naturally, with the growing benefits of technology, the Internet and network configurations comes the growing danger of security breaches, identity theft and cyber crimes. Unfortunately, electronic theft is becoming a greater danger to many businesses across the globe, so how do business owners keep their data safe and secure? One way to keep sensitive information secure is to constantly improve network security and to stay ahead of the game.

Every day we hear that computer viruses, hacker, and other security breaches have found new ways to steal identities, financial records and other information we thought previously secure. Because of the increase in such cyber crimes, data protection laws have tightened and the punishments hardened. With this comes the need for all businesses to take data security very seriously.
It is extremely important to improve network security for your business on a regular basis. Aside from encrypted pages and passwords, there is a multitude of ways to improve network security for your business which include firewalls and other infrastructure protective measures. Education, information and action are key elements to improving any network’s security.
Before a business can adequately protect its network, it is important to understand that there is no such thing as a completely secure system, as technology is always changing. However, to stay one step ahead and keep the network secure, business owners and their IT department should learn and understand any and all risks associated with security standards and network systems.
Network security can always be improved. After understanding the risks involved in any network, network operators should be educated and informed. It is important for network operators to keep an eye out for operational anomalies. Any anomaly is usually an indication that something is wrong and there may be a security breach. In addition to educating operators, it is important for operators to know and understand the risks associated with your existing security standards. Risk mitigation is essential in improving network security.
Organisation is also crucial to improving network security. It is an excellent idea to employ both control system engineers and IT specialists to work together to maintain the network. If you are unable to employ individuals, you may outsource the positions. The team should schedule risk analyses on a regular basis, implement change control and monitor the network regularly. Additionally, create policies and procedures that describe and outline risk mitigation, alert vectors and actions to be taken if and when any type of security breach is detected is smart. Furthermore, your operating staff should know exactly who to contact in the case of a breach or attack on the security of the network.
Following industry guidance and suggestions is also a good way to improve network security. One of these suggestions is to create a single point failure matrix, which is often critical during possible threats or attacks. The network security industry is always announcing new ways to secure and protect networks, configurations and information.
Staying informed has never been more important than when a business needs to improve network security. Though integrating the latest technologies and protections for your network is smart, regular security audits, education, and monitoring are all key ways to improve network security.

Disable the Guest Account and Administrator account on your computer. Create an account with Administrative privledges and give it a complex password. Use an account with restricted or Power-User privileges.
Turn on WEP and WPA on your wireless router, provided you are using wireless.
If you can, setup your router to block all wireless MAC addresses except the one of your laptop.
Give the router a complex password.
Setup the router to port forward to all un-needed open ports to a non-existant IP on your network.
Try to use sites with secure logins. "https://"
Try to have many complex passwords as you can.

Btw, what’s the common use for this? I’m using arpspoofing techniques, but it’s frustrating, I’m trying to understand how it works better. I can forward packets from one IP to me, but how do you do a whole subnet?

I suspect that either program contains some of both subjects. You can't secure a network that has been poorly engineered and the best engineered network without top notch security is reduced to a lousy network. Beware of excess specialization!
Both fields are quickly moving but Network Security is truly an arms race. There are lots of best practices in network engineering but they don't change at the same pace.
Fine network engineering is important to the efficiency of the business but network security is critical to the life of the business and that gives it strategic priority in information intensive companies. For example, network engineering usually reports to a networking manager who reports to MIS who reports to the CIO. In most companies with intensive IT structures (like brokerage) there is a seperate Chief Security Officer (CSO) because of the strategic priority of security.
Also, I suspect there are many more trained network engineers than trained network security people (serious security threats began to rise exponently only about 1997)
So I would suggest the diploma read "security" but you take enough network engineering to speak the lingo and understand the basic architectural choices.
To help you evaluate this advice I will tell you I was founder of the company that built out 700 of the 1000 largest global WANs in the 1980s and early 90s. I worked directly with the CIOs of the top firms when this all got started (and before there were CSOs). Good luck, either choice works.

Small packets can slip through a firewall, where there are rules for sting comparisons.
i.e. you have a rule to block packets containing the string worm.exe
but the message is so split up/fragmented, worm is in one packet, .exe is in an other, therefore it doesen’t match the rule set and allowed by the firewall.

The software that accompanies the latest routers automatically go through the process of setting up some either WEP/WPA or some other security measures on the router. The older software did no such thing and so the routers were completely open and transparent.
This is would the FIRST thing to check on the home network. Take a laptop with WiFi built-in and you should be able to see your CEO's wireless network and quickly see if it's secure or entirely open.
If it's open, then that's one avenue for people to get into her network and take whatever they want.
