I want to build a local intranet for free tutorial videos where users can connect with wifi. Just connect and learn. How possible is this?
This might be looking little vague if you want to do this from scratch you can host a website within intranet for that you may need to Create webpages using HTMLCSS with your requirements and store them in a folder Include the folder created in step1 in root folder of server (i.e Cinetpubwwwroot for IIS and htdocs for abyss) italic Access your webpage in connected clients in wifi network (intranet). ordered-list
How do I learn ethical hacking for free?
If you want to learn ethical hacking you need a lot of things the basics will get you started. This list is what got me started. aboutputer hardware i would take A+ your friend theputer See when you take it apart and get use to it its not scary is it? Some of you will say that A+ Security+ Network+ Linux+ Network+ CEH is not required none of these courses are its just that they teach the skills you would need without having to google ever single one. more than one programming language programming languages for this i would start with Python then move to something a little moreplex but do not push to yourself to much at once and to hard when you know some programming languages move to Java then if you wish move to c its hard to give aplete list because ever hacker and programmer is different and languages and syntax change a lot pick a language you like do not study one you hate just because your friends say that all hackers know that language and its awesome pick a language you like and learn it learn more than one if you can you should be able to program in multiple languages Python is bing a very popular scripting language Just in case you did not know A Scripting Language is a language such as Bash and Python to automate tasks such as network analysis. a little bit of a native scripting language on your OS this could be Bash(Linux) PowerShell(Windows) this will be useful for scripting tools to be used for your system or the ability to script a backdoor in python or powershell depending on what is installed on the system if your target is windows then powershell is going to be installed and Bash will be useful for a Linux machine automating a script to copy files download a script for post exploitation from a Exploit database orpiling a file uploaded to theputer or server via something like FTP(File Transfer Protocol)whatever you cane up with or to script a tool you found a exploit for or fixing a broken or outdated tool. 4. Be Creative. Creativity is required to be a hacker because as defenders of a network areing up with new defenses to protect there systems you as a hacker need to find ways to change the ways these systems work and need a way to figure out how to upload a shell to that Box. some Computer Networking. Learn things like ARP Firewalls NAT DNS Subnet DHCP IP OSI model TCP TCP UDP HTTP HTTPS etc. This will be helpful when trying to understand how a attack works Network+ is very helpful. 6. Realize that Hacking is not like its done in the movies or displayed on your favorite News Platform Hacking andputers in general is such a large topic that no one is a expert this is why hacking is multiple subjects like social engineering web server hacking etc hacking is not even limited to aputer. about s of attacks like days Phishing MITM File inclusions Buffer overflows etc. some reverse engineering this will help in understanding code and changing the way a program works. give up. No one starts out perfect they start as amateurs and beginners. if not to use a handle or not to.
I do not want to update WordPress as it is not compatible with some of the plugins, what could be the solution for security issues if happen?
Without crying wolf there are really a few different s of plugins (being simplistic here) Super amazing free plugins that are kept up to date all the time and we love them and there are neverpatible issues. They are maintained by super Wordpress ninjas who in some cases (possibly) make a bit of cash from their actual plugin website (good for them) Paid plugins (also could be amazing) that are also kept up to date because the people paid for them. The Others (ref Lost TV Series). At the end of the day a plugin is a block of nice code that allows you do something on your WP site easier than you coding it yourself. But often someone enthusiastically creates a plugin supports it for a few revisions and well stops as they lose interest get a job win the lotto whatever. In the last case this leaves your site open to vulnerabilities or worse still something just doesn't work anymore. The scum sucking hackers know this and watch out for this. So it does leave you open to being hacked. Does it mean that you will be hacked the day after you don't update. No but it is still a probability. Finally there are plenty of garbage supported italic plugins out there that look the part that won't do you any favours on a security front either. So my advice is the following If the plugin is important to you then try and contact the plugin owner and see if he is going to update (most often not). This may mean you have to find an alternative. If it is really really important to you you might think of taking on the plugin and bringing it up to date. Not a small task. Most probably get another supported plugin and fix all the things that having a similar but not the same plugin brings. Hope that helps Let me know if it doesn't Kieran
What are the most productive ways to spend time on the Internet?
I think a lot of these answers miss the point of the question. The real issue isn't that there's a paucity of useful webpages on the internet it's that taking advantage italic of those webpages is difficult. What does it say about human beings that we really italic can get an Ivy League education for free online but nearly nobody does it? The Coursera and Udacity and Khan Academy attrition rates are so phenomenal that it makes thepletion rates look like round-off errors. We live in an attention-deficit culture and the solution isn't better websites it's better humans. In view of spending your time more effectively I suggest the following tipsn Completely cut Facebook Reddit Twitter and any other social sites out of your life. If you are unable to do this strictly regulate the total time spent on these sites to 3 minutes to an hour each day. You can download Chrome extensions to help you with this like StayFocusd s . But I cannot emphasize enough how much these sites will ruin your life. Everyone alwayses to the defense of social media with excuses like well I use Facebook to keep in touch with my high school friends and relatives overseas or Twitter is how I stay up-to-date with current events or you can learn lots of great things with specialized subreddits and so on. Yet when you look at a distribution of how people actually italic allocate their time nearly none of it is spent doing the very things that people point to when they justify their behavior. It's always just mindless scrolling animated gifs cat videos the first twenty seconds of a really neat lecture and so could be a more devastating rebuke of social media than the fact that nobody uses it for the reasons it was designed? This is of course auxiliary to the more important reality that research on Facebook consistently shows that it makes everyone more sad and less fulfilled with life on average.n To-do lists. There may be nothing more insanely effective than a to-do list. Write down what you have to do prioritize the list by difficulty and be excruciatingly detailed when you write down your objectives. Don't get fancy don't use Evernote or a Chrome Extension or some app just use paper and pen. Don't write Finish research paper on ethics. Write Write one page on Chapter 3 of Peter Singer's 'Practical Ethics. The smaller more discrete the tasks the more superable they be. Also plan how italic you are going to efficiently procrastinate in between the tasks. Write play chess watch a Noam Chomsky lecture do one lesson of DuoLingo and so forth in between big tasks. Take a power nap if you're too exhausted to be efficient with your procrastination. nnRemember when you don't plan your time you fail to take advantage of opportunities that avail themselves and you go for the path of least resistance -- which usually happens to be AngryBirds and YouTube videos.n
What is a virus?
Aputer virus is malicious code that replicates by copying itself to another programputer boot sector or document and changes how aputer works. The virus requires someone to knowingly or unknowingly spread the infection without the knowledge or permission of a user or system administrator. In contrast aputer worm is stand-alone programming that does not need to copy itself to a host program or require human interaction to spread. Viruses and worms may also be referred to as malware .A virus can be spread by opening an email attachment clicking on an executable file visiting an infected website or viewing an infected website advertisement . It can also be spread through infected removable storage devices such USB drives . Once a virus has infected the host it can infect other system software or resources modify or disable core functions or applications as well as copy delete or encrypt data. Some viruses begin replicating as soon as they infect the host while other viruses will lie dormant until a specific trigger causes malicious code to be executed by the device or system. Many viruses also include evasion or obfuscation capabilities that are designed to bypass modern antivirus and antimalware software and other security defenses. The rise of polymorphic malware development which can dynamically change its code as it spreads has also made viruses more difficult to detect and identify. Types of viruses File infectors. Some file infector viruses attach themselves to program files usually selected or .exe files. Some can infect any program for which execution is requested including .sys .ovl .prg and .mnu files. When the program is loaded the virus is loaded as well. Other file infector viruses arrive as wholly contained programs or scripts sent as an attachment to an email note. Macro viruses. These viruses specifically target macro languagemands in applications like Microsoft Word and other programs. In Word macros are saved sequences formands or keystrokes that are in the documents. Macro viruses can add their malicious code to the legitimate macro sequences in a Word file. Microsoft disabled macros by default in more recent versions of Word; as a result hackers have used social engineering schemes to convince targeted users to enable macros and launch the virus. As macro viruses have seen a resurgence in recent years Microsoft added a new feature in Office 216 that allows security managers to selectively enable macro use for trusted workflows only as well as block macros across an organization. Overwrite viruses. Some viruses are designed specifically to destroy a file or application's data. After infecting a system an overwrite virus begins overwriting files with its own code. These viruses can target specific files or applications or systematically overwrite all files on an infected device. An overwrite virus can install new code in files and applications that programs them to spread the virus to additional files applications and systems. Polymorphic viruses. A polymorphic virus is a of malware that has the ability to change or mutate its underlying code without changing its basic functions or features. This process helps a virus evade detection from many antimalware and threat detection products that rely on identifying signatures of malware; once a polymorphic virus' signature is identified by a security product the virus can then alter itself so that it will no longer be detected using that signature. Resident viruses. This of virus s itself in the memory of a system. The original virus program isn't needed to infect new files or applications; even if the original virus is deleted the version stored in memory can be activated when the operating system loads a specific application or function. Resident viruses are problematic because they can evade antivirus and antimalware software by hiding in the system's RAM . Rootkit viruses. A rootkit virus is a of malware that installs an unauthorized rootkit on an infected system giving attackers full control of the system with the ability to fundamentally modify or disable functions and programs. Rootkit viruses were designed to bypass antivirus software which typically scanned only applications and files. More recent versions of major antivirus and antimalware programs include rootkit scanning to identify and mitigate these s of viruses. System or boot-record infectors. These viruses infect executable code found in certain system areas on a disk. They attach to the DOS boot sector on diskettes and USB thumb drives or the Master Boot Record on hard disks. In a typical attack scenario the victim receives storage device that contains a boot disk virus. When the victim's operating system is running files on the external storage device can infect the system; rebooting the system will trigger the boot disk virus. An infected storage device connected to aputer can modify or even replace the existing boot code on the infected system so that when the system is booted next the virus will be loaded and run immediately as part of the master boot record . Boot viruses are lessmon now as today's devices rely less on physical storage media. History ofputer viruses The first knownputer virus was developed in 1971 by Robert Thomas an engineer at BBN Technologies. Known as the Creeper virus Thomas' experimental program infected mainframes on ARPANET displaying the tele message I'm the creeper Catch me if you can.
