Introduction to User Access Security Commonly Asked Questions Policy Issues User Access Security Countermeasures User Access Security Checklist A person with a "need-to-know" has been designated by school officials as having a legitimate educational or professional interestin accessing a record. Introduction to User Access SecurityUser access security refers to the collective procedures by which authorized users access a computer system and unauthorized users are kept from doing so. To make this distinction a little more realistic, however, understand that user access security limits even authorized users to those parts of the system that they are explicitly permitted to use (which, in turn, is based on their "need-to-know"). After all, there is no reason for someone in Staff Payroll to be given clearance to confidential student records. It Really Happens!Kim approached Fred cautiously. As the security manager, she knew how important it was to gather information completely before jumping to conclusions. "Fred, my review of our computer logs shows that you have been logging in and looking at confidential student information. I couldn't understand why someone in Food Services would need to be browsing through individual student test scores, so I thought I'd come by and ask you."Fred looked up at Kim as he if was surprised to be entertaining such a question. "Are you forgetting that I'm authorized to access student records?""You're authorized to access specific elements that relate to a student's free- and reduced-price lunch eligibility," Kim clarified. "That's the limit of your need-to-know.""I didn't know that my access was limited," Fred asserted honestly. "I figured that if my password got me into a file, it was fair game."Kim paused, realizing that it might be reasonable for Fred to have assumed that he was allowed to read a file if his password gave him access. "Hmm, I see your point, Fred, but in truth you shouldn't be accessing student record information that isn't related to your legitimate educational duties. I'm not going to make a big deal of it this time, but from now on, limit your browsing to the free- and reduced-price lunch information. In the meantime, I'm going to send a memo out to staff reminding them what need-to-know really means.""And you might want to reconsider how our password system works," Fred added. "It would have beenvery clear to me that I had no business in a file if my password wouldn't get me in."An organization cannot monitor user activity unless that user grants implicit or explicit permission to do so! While there is no question that an organization has the right to protect its computing and information resources through user access security activities, users (whether authorized or not) have rights as well. Reasonable efforts must be made to inform all users, even uninvited hackers, that the system is being monitored and that unauthorized activity will be punished and/or prosecuted as deemed appropriate. If such an effort is not made, the organization may actually be invading the privacy rights of its intruders!An excellent way of properly informing users of monitoring activities is through the opening screen that is presented to them. By reading a warning like the one that follows, users explicitly accept both the conditions of monitoring and punishment when they proceed to the next screen. Thus, the first screen any user sees when logging into a secure computer system should be something to the following effect:Never include the word "Welcome" as a part of the log-in process--it can be argued that it implies that whoever is reading the word is, by definition, invited to access the system. W A R N I N G !This is a restricted network. Use of this network, its equipment, and resources is monitored at all times and requires explicit permission from the network administrator. If you do not have this permission in writing, you are violating the regulations of this network and can and will be prosecuted to the full extent of the law. By continuing into this system, you are acknowledging that you are aware of and agree to these terms. Commonly Asked QuestionsQ. Is it possible to have a secure system if you have employees who telecommute or work otherwise non-traditional schedules?A. Yes. While particular countermeasures might need to be adjusted to accommodate non-traditional schedules (e.g., the practice of limiting users to acceptable log-in times and locations), a system with telecommuters, frequent travelers, and other remote access users can still be secure. Doing so may require policy-makers to think more creatively, but each security guideline needs to be customized to meet the organization's needs anyway (see Chapter 2). Q. Is the use of passwords an effective strategy for securing a system?A. Just because password systems are the most prevalent authentication strategy currently being practiced doesn't mean that they have become any less effective. In fact, the reason for their popularity is precisely because they can be so useful in restricting system access. The major concern about password systems is not their technical integrity, but the degree to which (like many strategies) they rely upon proper implementation by users. While there are certainly more expensive and even effective ways of restricting user access, if risk analysis determines that a password system meets organizational needs and is most cost-effective, you can feel confident about password protection as long as users are implementing the system properly--which, in turn, demands appropriate staff training (see Chapter 10). Q. Are all of these precautions necessary if an organization trusts its staff?A. Absolutely. While the vast majority of system users are probably trustworthy, it doesn't mean that they're above having occasional computing accidents. After all, most system problems are the result of human mistake. By instituting security procedures, the organization protects not only the system and its information, but also each user who could at some point unintentionally damage a valued file. By knowing that "their" information is maintained in a secure fashion, employees will feel more comfortable and confident about their computing activities. Initiating security procedures also benefits users by:
Hackers Have Global Coalitions Now: We Want Alike To Break Them
While fake news sites are not new, they are being used with increasing sophistication for political purposes. Progovernment actors in Iran have long created sites like persianbbc.ir to mimic the look of the authentic bbcpersian.com, filling them with conspiracy theories and anti-Western propaganda. More recently, Iranian hacker groups have established websites with names like BritishNews and AssadCrimes as part of more elaborate social-engineering schemes. The latter contained articles lifted from a Syrian opposition blog and was falsely registered under the name of a prominent opposition activist. Hackers created email addresses and social media profiles linking to the fake publications in order to communicate with government opponents and human rights defenders and map out their social networks. Once trust was established, the hackers targeted victims with so-called remote access trojan (RAT) programs and gained access to their devices.
Streaming video in real time has become increasingly popular since the launch of a now-defunct mobile app, Meerkat, in early 2015. Many apps have since added live-streaming features, and deliver content to large global networks. The ability to stream live content directly from a mobile device without the need for elaborate equipment or a distribution strategy has made the technology more accessible. Dedicated news outlets and other content producers also continue to stream live content from their own websites, and some are now doing so in conjunction with apps and social media platforms. Often this allows them to bypass regulations specific to traditional broadcasters, and to reach new audiences.
A black hat hacker is someone who maliciously searches for and exploits vulnerabilities in computer systems or networks, often using malware and other hacking techniques to do harm. These stereotypical hackers often break laws as part of their hacking exploits, infiltrating victims' networks for monetary gain, to steal or destroy data, to disrupt systems, to conduct cyberespionage or just to have fun.
Because things are never black and white, enter the grey hat hacker. A fusion of black and white, grey hats exploit security vulnerabilities without malicious intent, like white hats, but may use illegal methods to find flaws. They may even release the vulnerabilities to the public or sell details about them for a profit like a black hat would. Grey hat hackers also often hack without the target's permission or knowledge. The grey hat description is also used to categorize hackers who may, at one stage in life, have broken the law in their hacking activities but have since made the move to become a more ethical, white hat hacker.
A child is unlikely to know they've been groomed. They might be worried or confused and less likely to speak to an adult they trust. If you're worried about a child and want to talk to them, we have advice on having difficult conversations.
As we recently surpassed $100 million dollars in bounties, we want to continue the celebration with this list of 100 tools and resources for hackers! These range from beginner to expert. Most are free but some cost money. Read all about them here.
The hackers claim that you have been watching adult videos from your computer while the camera was on and recording. The demand is that you pay them, usually in Bitcoin, or they will release the video to family and/or colleagues. 2ff7e9595c
