Recommended: What is the primary value of a firewall

In the last ten years, there have been many software vulnerabilities that have caused thousands of dollars to businesses. Many of their resources have been breached, and those malicious attacks have gotten better over the years. Back in the day, the job of a system administrator sometimes involved dealing with malware and other infectious software. However, security threats have become heavier on businesses today, and they depend on these IT professionals to do more than just updating the network with the latest security patches (Belovich, S. 2010).
Consequently, having a strong IT security environment as well as having the experience to maintain it, is an important asset in most network infrastructures today. The evolution of the Internet …show more content…

There might be some businesses that refuse to spend more money than they should to update their security system, but whenever something happens, they end up regretting it. So it is crystal clear that IT security is an essential asset that needs to be protected with the right equipment or software. Many businesses cannot avoid the realization that they have to interact with a growing number and wider variety of viruses, malware, threats, and other …show more content…

In large network architectures though, NAT is not enough. Hiding a company’s IP address is definitely not enough. Therefore, using firewalls is important because firewalls stop or at least try to stop any malicious threats from coming in the network. Unlike the basic task of NAT, the firewall actually takes a look at possible vulnerabilities from incoming traffic so that it can prevent them from coming in any further. One perfect example of the appropriate usage of firewalls is the big role it plays in VPN connections. The user can send any type of information in between this secured tunnel without any worries, because this information is properly encrypted. Now, there are different types of firewalls available today that can be quite costly, but Cisco has the best solutions so far in my opinion. Unfortunately, firewalls are quite expensive for large organizations, since they have to protect larger assets depending on how many users will be using the network (Stewart, J.

    It is best to prevent security incidents from occurring in the first place – therefore prevention should be a top priority for the IT staff at CEG. The National Institute of Standards and Technology (NIST) recommends five main categories of incident prevention; risk assessments, host security, network security, malware prevention, and user awareness training (Cichonski P., Grance T., Millar T., & Scarfone K., 2012 p.24). Risks of the various types of possible security incidents should be identified and prioritized based on likelihood and potential harm. Risk assessment should be periodic and ongoing. Host security is achieved by hardening each host on the network. Host hardening includes keeping current on the latest software patches, enabling and monitoring audit logs, and assigning permissions based on a system of least privilege. Network security is primarily concerned with securing the perimeter of the network to prevent unauthorized intrusion. This includes the use of firewalls, intrusion detection systems (IDS), securing VPN, and blocking unnecessary ports. All hosts on the network must run and regularly update malware protection software. And all employees should...

    Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what

    A public utility company employed SecureState to repair their internal and external network security. Consequently, SecureState was able to access the network due to a variety of exploits. Many threats would not be present if systems were updated with the latest operating software and patches and were properly configured. This engagement revealed several critical problems within the client’s system, allowing SecureState to gain access to more resources than intended. The improperly segmented networks combined with easily exploitable vulnerabilities can allow attackers to gain access to entire networks potentially causing untold levels of damage.

    As electronic commerce, online business-to-business operations, and global connectivity have become vital components of a successful business strategy, enterprises have adopted security processes and practices to protect information assets. But if you look at today's computing environments, system security is a horrible game of numbers: there are currently over 9,223 publicly released vulnerabilities covering known security holes in a massive range of applications from popular Operating Systems through to obscure and relatively unknown web applications. [01] Over 300 new vulnerabilities are being discovered and released each month. Most companies work diligently to maintain an efficient, effective security policy, implementing the latest products and services to prevent fraud, vandalism, sabotage, and denial of service attacks. But the fact is you have to patch every hole of your system, but an attacker need find only one to get into your environment. Whilst many organisations subscribe to major vendor's security alerts, these are just the tip of the security iceberg and even these are often ignored. For example, the patch for the Code Red worm was available some weeks before the worm was released. [02]

    The nation has become dependent on technology, furthermore, cyberspace. It’s encompassed in everything we deliver in our daily lives, our phones, internet, communication, purchases, entertainment, flying airplane, launching missiles, operating nuclear plants, and implicitly, our protection. The more ever-growing technology empower Americans, the more they become prey to cyber threats. The United States Executive Office of the President stated, “The President identified cybersecurity as one of the top priorities of his administration in doing so, directed a 60-day review to assess polices.” (United States Executive Office of the President, 2009, p.2). Furthermore, critical infrastructure, our network, and internet alike are identified as national assets upon which the administration will orchestrate integrated cybersecurity policies without infringing upon and protecting privacy. While protecting our infrastructure, personal privacy, and civil liberties, we have to keep in mind the private sector owns and operates the majority of our critical and digital infrastructure.
