Botnet is a term for a collection of software robots, or bots, that run autonomously and automatically. Below are some of the more common policies that organizations should put in place. As a result, the files – many containing highly confidential health-related information – were widely exposed on the internet. Be suspicious of strange links and attachments. The business didn’t use sufficient measures to detect unauthorized access to its network. A good information-security policy lays out the guidelines for employee use of the information resources of the company and provides the company recourse in the case that an employee violates a policy. A good example of a blind attack can be found at http://wiki.cas.mcmaster.ca/index.php/The_Mitnick_attack. Controls are also categorized by the type of control they are: All three categories of controls can be any one of the three types of controls; for example, a preventive control can be administrative, physical, or technical. appear. Put procedures in place to keep your security current and address vulnerabilities that may arise. Technical controls are extremely important to a good information security program, and proper configuration and maintenance of these controls will significantly improve information security. Risk management and security policies will be detailed later in this chapter. In the past, the typical DoS attack involved a single attempt to flood a target host with packets. Savvy companies think through the implication of their data decisions. Which of the following network security mitigations involves login? Tunnel mode provides protection to the packet which is finished. In each case, the business could have reduced the risk to consumers’ personal information by implementing reasonable security policies when data is en route. Online password cracking involves, as an example, different combinations of password on a live system. Upon successful completion of this chapter, you will be able to: Please note, there is an updated edition of this book available at https://opentextbook.site. appear. Attackers typically accomplish this by exhausting some resource limitation on the network or within an operating system or application. Apply sound security practices when developing new products. This type of attack is not new. Organizations of all kinds are taking advantage of offerings such as Software as a Service (SaaS) and Infrastructure as a Service (IaaS) to reduce costs and simplify the deployment of new services and applications. Increasing network connectivity meant that viruses like the Morris worm nearly wiped out the early internet, which began to spur the creation of the first antivirus software. What information does the organization actually have? Consider also supporting identified email initiatives such as DomainKeys Identified Mail (DKIM); these initiatives are beyond the scope of this book. Ask your instructor if you can get extra credit for backing up your data. Widespread IP internetworking increases the probability that more attacks will be carried out over large, heavily interconnected networks, such as the Internet. A recent study found that the top three passwords people used in 2012 were. In the Dave & Buster’s case, for example, the FTC charged that the company failed to adequately restrict third-party access to its network. The algorithm compares this hash to the hash stored on the system. Another cleaver man-in-the-middle attack is for the hacker to successfully introduce himself as the DHCP server on the network, providing its own IP address as the default gateway during the DHCP offer. Specifying how long passwords are valid before the must be changed. Botnets are used for spam, data theft, mail relays, or simply for denial-of-service attacks (ref: Zeus botnets reached an estimated 3.6 million. High-value information assets should be secured in a location with limited access. 1. The company could have reduced that risk by sufficiently segmenting its network. But according to the complaint, it continued to store that data for up to 30 days – long after the sale was complete. But once the information reached the server, the company’s service provider decrypted it and emailed it in clear, readable text to the company’s headquarters and branch offices. Periodically, the Fed announces a new discount rate. They are often part of botnet attacks, which try to raise privilege levels, create network shares, and steal data. Often, the command and control takes place via an IRC server or a specific channel on a public IRC network. It had no physical branch bank offices and could only be accessed online. An asset is anything of value to an organization. Distilling the facts of those cases down to their essence, here are ten lessons to learn that touch on vulnerabilities that could affect your company, along with practical guidance on how to reduce the risks they pose. For example, suppose that a vulnerability exists in a piece of software, but nobody knows about this vulnerability. The combination of CPU power and interest in privacy has led to the development of techniques for hiding messages in digital pictures and digitized audio. The frequency of backups should be based on how important the data is to the company, combined with the ability of the company to replace any data that is lost. Chapter 5: Networking and Communication, 6. The security system design must accommodate the goals of the business, not hinder them. A threat is a potential danger to information or systems. This may be done to eliminate the possibility of employees watching YouTube videos or using Facebook from a company computer. In TRENDnet, for example, the FTC charged that the company failed to test that an option to make a consumer’s camera feed private would, in fact, restrict access to that feed. Antivirus software and spyware-removal software cannot protect against pharming. The recipient then uses the private key to decode it. One simple solution for this is to set up an account with an online backup service, such as Mozy or Carbonite, to automate your backups. Notice that some threats are not malicious attacks. FTC cases offer advice on what to consider when hiring and overseeing service providers. Start banking online using Axis Bank. These brute force attacks work by typing endless combinations of characters until hackers luck into someone’s password. The password for a wireless security network is also known as the _____. In the e-mail, the user is asked to click a link and log in to a website that mimics the genuine website and enter their ID and password, which are then captured by the attacker. Threats are also becoming persistent. The client selects and transmits an initial sequence number. Each year, the Ombudsman evaluates the conduct of these activities and rates each agency’s responsiveness to small businesses. After the hacker accesses handler systems, the hacker installs zombie software on them to scan, compromise, and infect agent systems. For instance, a sensitive file could mistakenly be given global read access. http://www.networkworld.com/news/2009/072209-botnets.html, http://wiki.cas.mcmaster.ca/index.php/The_Mitnick_attack, http://www.wisegeek.com/what-is-a-botnet.htm, CCNA Collaboration CICD 210-060 Official Cert Guide: Managing Endpoints and End Users in CUCM, Cisco Networking Academy Switched Networks Companion Guide: VLANs, Fundamental concepts in network security, including identification of common vulnerabilities and threats, and mitigation strategies, Implementation of a security architecture using a lifecycle approach, including the phases of the process, their dependencies, and the importance of a sound security policy. The failure of a host or application to handle an unexpected condition, such as maliciously formatted input data or an unexpected interaction of system components. The most common way to identify someone is through their physical appearance, but how do we identify someone sitting behind a computer screen or at the ATM? As a result, hackers could use one in-store network to connect to, and access personal information on, other in-store and corporate networks. An IDS can be configured to watch for specific types of activities and then alert security personnel if that activity occurs. A good backup plan should consist of several components. Secure remote access to your network. A comprehensive database of more than 17 network security quizzes online, test your knowledge with network security quiz questions. Employee training: One of the most common ways thieves steal corporate information is to steal employee laptops while employees are traveling. Good luck! Examples of these influences included the fear of a new worm outbreak, the uncertainty of providing web services, or doubts that a particular leading-edge security technology would fail. Biological and Biomedical Secure paper, physical media, and devices. That’s the lesson to learn from a number of FTC cases. By making conscious choices about the kind of information you collect, how long you keep it, and who can access it, you can reduce the risk of a data compromise down the road.
