Several complaints against the performance of the local network and website has prompted a full security review to determine the root cause. Many threats were itemized for the server, workstations, and website; but the most severe cross all three aspects.
As already experienced, the likelihood of each threat is high. That is not the important aspect to discuss; the root cause that allows these threats to be successful is the most pressing issue. The lack of control, lack of monitoring, and lack of security measures is the root problem that has lead to mass security breaches inside the office network.
Common Threat Causes
The core issue with all theats listed is the lack of network segmentation, lack of security controls, and a lack of monitoring. This can be addressed simply and easily with little overhead for IT support. In-fact, many of these measures may assist in a workload reduction for IT staff as they will end many reactionary support calls from users.
System Privileges
Systems should allow users the least amount of system rights to perform their functions. Arbitrary software installations raise the risk of both unwanted & malicious applications being installed either with or without the user’s knowledge and the potential of the organization accidently breaching a software vendor’s end-user license agreement. Software installation should be handled by having a central catalog and allowing IT staff to determine what is acceptable for use.
Without control of system privileges, attacks that include privilege escalation has a significantly higher probability of success. This can lead to malware infections, backdoor intrusions, data exfiltration, user spying, and lateral attacks.

Using Nagios and Cacti will also improve detection of system outages and monitor performance on a more granular level.
Puppet, WSUS, & Group Policy
Using Puppet and WSUS to manage system and application patches will automate the updating of systems and provide a consistent platform across all assets. Administrators will be automatically notified if systems stay out of date and allow personnel to be more proactive in their IT support efforts.
Conclusion
System security, while an ever-changing landscape, is easier to defend against non-persistent, non-targeted attacks. These suggestions cost little more than time, some minor hardware, and a slight network redesign. The end result will greatly enhance the ability of the IT staff to support and defend the network, overall saving the organization money and time.
However, I feel users had a different vision/perspective on security mechanisms and they trusted each other during those times and did not have to worry about protecting their information (this is how exactly, one person’s ignorance becomes another’s person’s - hacker, here bliss). This book helps us to understand the vulnerabilities; its impacts and why it is important to address/ fix those holes.
Security of the companies data is one of the most important components which allows the business to perform its day to day operation using various networking devices, services that absolutely needs to be protected from intruders. Some of these devices include online transactions, the exchange of data between users and clients both internal and external and external web data needs to be secured. There are several polices that would need to be configured such as a web sever and firewall configurations. However, with these configurations the first and most important task is to identify any vulnerabilities or loopholes in security within the company. The company has both LAN (Local Area Network) and WAN (Wireless Local Area Network) and a web sever. These resources need to be secured at all times from hackers or anyone else by implementing the appropriate security measures.
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
The topic of network security is a reoccurring theme in today’s business world. There is an almost unfathomable amount of data generated, transmitted, and stored every day. Unfortunately the media and traditional reporting sources these days typically only focus on outside threats such as hackers. Many people completely overlook the insider threats that are present and can potentially pose and even bigger threat then any outside source. One of the acronyms that is constantly repeated in the security industry is the principle of CIA or confidentiality, integrity, and availability. Authorized users, whether by accident or through malicious acts, are in a unique position to threaten all three aspects of CIA.

What is the worst that could happen to a large insurance and financial corporation with facilities in several states? Exploring the seven domains of a typical IT infrastructure leads to several possibilities. One possible scenario for each of the seven domains, user, workstation, LAN, LAN-to-WAN, remote access, WAN, and system/application will be explored in depth and taken to the furthest worst-case scenario.
Hardware, software, support and maintenance costs grow each year with multiple systems in each local region running different types of software and hardware. The application and hardware support teams are larger than could be possible with one integrated solution.
Therefore, cyber-attacks causing tremendous damage to organizations along with customer spreading fear among
However, let us not exclude the ever present attacks of cybersecurity in the workplace, as it too has become an ever consuming global issue, in every workplace. And finally, let us see what measures should to be taken to make the workplace and its data safer for all. With violent attacks becoming a common site in the workplace, we can study these
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]
Network Security is the protection of the computer’s network though out the entire infrastructure. It can protect very important information and computer files to help prevent theft, spyware, malware, viruses, and more. Depending on if you have a public or private network, can determine what type of security settings you need for your network. All people are different on what they want to have secured or not, but most people do not know how to prevent people or things from getting in their network. “You must have a general understanding of security terminology and specifications as it relates to configuring hardware and software systems.”(Roberts, Richard M. 599). That quote states that by knowing and understanding security terms and specifics, you can
According to a recent research conducted by renowned Security Professionals, the major causes of data breach can be categorized into: 3.1 MALICIOUS ATTACKS Malware and hacking are the most potent and long-established causes of security breaches. Malware attacks and data loss are growing concerns for businesses around the world. To give a clear example, Zeus Trojan was modeled to steal financial information from the system influenced by it. By means of website monitoring and key logging, the malware identified the keystrokes used to log in and swiped information. 3.2 HUMAN FACTOR
There are numerous network security devices and tools available to aid in computer network defense, and these tools are often relied upon for protecting against increasingly sophisticated, stealthy, and damaging attacks. When acting alone, the current generation of security devices has an exceedingly difficult time providing an effective defense against such threats, and the situation is particularly grim for targeted or novel attacks.

It is also useful to consider not only these specific threats, but also the underlying themes that are of particular concern in recent years. Three such themes are terrorism, identity theft and internal fraud (that is, fraud committed by employees or other “insiders” in the organization).
