Firewalls are good and help against websites that are illegitimate. It’s also good to have an antivirus on your computer to help protect against people who are trying to hack into your system. Perhaps someone is trying to gain access to your financial information; the antivirus stops them from getting in. Always make sure that when you are checking your e-mail and receive an e-mail with an attachment if you do not know who it is from do not open it. I don’t even open e-mails from people I don’t know whether it has an attachment or not.
The main differences between the two are the speeds that they operate and the type of key that they use. Using a complex password with either encryption type will help protect against any brute force attacks. A hacker can compromise encrypted data by using multiple brute force attacks. Symmetric encryption is one the older and better techniques that is used to encrypt and decrypt all of the messages. This specific type of encryption uses a secret key that the sender and receiver must have.
VPN outfits its privacy by way of channeling and security measures. Channeling is a way that packets from one protocol are enclosed inside another protocol. There are a lot of hackers these days sending viruses, malware, and other bugs. It is important for a company to stay protected so that they don’t lose private information or open viruses that could temporarily shut a company down. Remote-access VPNs allows you to securely access corporate resources like servers, computers, and multipurpose printers.
This should not be connected to the main location but its own entity. If something goes wrong you are secure because you have a back-up copy of the data. • Virus Protection software- Trying to avoid getting a virus and training employees to watch out for signs of virus can be very important, especially through email. Try to avoid opening an email that does not look familiar or looks strange. In Conclusion It is important for an organization to be aware of the risk of technology.
He can use the names or phone numbers listed in the DNS to gather more sensitive data. Internet Protocol Address range can also be of useful to the attacker. By knowing the IP range, the attacker can port scan and identify active machine on that network. Although IP address range finding is imposable to protect from hackers, there are still counter measures
Network safeguards should include the use of firewalls, encryption of data, the use of digital signatures or certificates as well as web security protocols. Intrusion detection systems use is a great way for the organization to identify attempts or actions to penetrate a system to gain unauthorized access (Sayles, 2013). The organization should also address the issue of ensuring the quality of data being collected, stored and used. Ensuring data quality is also essential to an effective security program and can be managed through monitoring and tracking systems. The organization should ensure they implement a business continuity plan as well as a disaster recovery plan to ensure that the organization can continue operating during an unexpected shutdown or disaster.
The ping sweeps and port scans are the two techniques that malicious computer users such as hackers that can use to compromise an Enterprise networks security and gain access to their proprietary data. The ping sweeps are performed to find an open-door into a particular end-point. A person usually can find all kinds of utilities on the internet to exploit the open-doors on the system and gain access to important and confidential files on the network. It is a good idea that we try to protect ourselves against all these types of activities on the network and to also try to conduct them ourselves that way we know that out networks are safe. The ping sweeps are what you really think they are.
Unit 13 I.T. Systems Troubleshooting and Repair Coursework Submission Task one MID WALES STEEL Organisational policies Security: security is a must for a large organisation, and the computers and other technical equipment that have information about the business stored onto that computer. Anti Virus Software: you would have to have anti-virus software on there to be safe. The last thing that you want is someone hacking into the devices and stealing information about your company and knowing your personal information, so having security on those devices is always a must. Individual login Ids and Passwords: every employee should have their own individual login Ids and passwords, to prevent other employees going on other employees work, and looking at their personal information.
Case Study 2: SCADA Worm Protecting the nation’s critical infrastructure is a major security challenge within the U.S. Likewise, the responsibility for protecting the nation’s critical infrastructure encompasses all sectors of government, including private sector cooperation. Mitigating the vulnerabilities between the private sector and government agencies comes with an effective IT Security Policy Framework which properly implemented can protect us from these attacks. The vulnerabilities, which vary among the products examined, include backdoors, lack of authentication and encryption, and weak password storage that would allow attackers to gain access to the systems (Zetter, 2011). The security weaknesses also make it possible to send malicious commands to the devices in order to crash or halt them, and to interfere with specific critical processes controlled by them, such as the opening and closing of valves.
Ping Sweeps and Port Scans Thesis Statements: In this paper I will talk about the danger that we are facing day by day from hackers and we will talk about two common network probes called Port scan and Ping Sweeps and how to protect ourselves from hem. Introduction: Ping sweeps and ports scans are common methods for hackers to try to break a network. As a system administrator this is a valid concern and for the boss this should not be a worry for him. The system administrator has a lot of steps to stop efforts from hackers to acquire any data by using ping sweeps and ports scans. If hackers are constantly thwarted and discouraged from penetrating your network they normally move on to another site.
