Computer Hacking Methods and Protection

Posted on Posted in computer, internet, website

Protecting your computer against hacking is different from protecting it against viruses that you accidentally or unknowingly invite into your computer that then cause damage in one form or another. Anti-hack is about protecting your computer against external entities that are deliberately trying to get into your computer to cause damage and to steal from you – or cause damage. Viruses are impersonal and hacking is personal.

Anti-Hack software is now out there for sale in addition to anti-virus software. These products protect you in ways that anti-virus software does not. Following are some examples.

DoS (Denial of Service) Attacks:

DoS attacks occur when too much traffic is directed to your company website at once. The web server essentially ‘chokes’ on the amount of traffic trying to squeeze into it’s network hardware. Attack scripts are easily downloadable and you do not need to be an experienced engineer to launch an attack. Upset customers seeking some sort of revenge or disruption, competitors interrupting your site, or these days, as in the recent major hospital attacks, the trend is to hold your web site hostage until some ransom is paid or some demand met. “Ransomeware” is a relatively new term, but it is gaining a lot of visibility in recent times.

SNMP (Simple Network Management Protocol) Attacks:

Akamai’s Prolexic Security Engineering and Response Team (PLXsert) recently issued a threat advisory warning of DDoS (Distributed Denial of Service) attacks abusing the Simple Network Management Protocol (SNMP) interface. PLXsert SNMP DDoS attack campaigns target various industries including consumer products, gaming, hosting, nonprofits, and software-as-a-service, mainly in the US (49.9%) and China (18.49%). The attackers used an online tool posted by the hacker group ‘Team Poison’. This latest wave of attacks targets devices running SNMP which by default is open to the public Internet unless that feature is manually disabled. Anti-hack software is now being created that help prevent SNMP attacks such as this by preventing the attacker from forcing network switching to secondary gateways.

SYN/AWK Attacks:

This is a little complex but basically, a SYN flood attack is similar to a Denial of Service attack in that there is request made to the web server that ties up its resources and makes it unavailable to other connections. When a computer or web browser tries to connect to a web site, what’s called a 3-way handshake is used to establish the connection between the two computers. In a SYN/AWK Flood attack, the computer offers its hand (1-way), the server reaches out to meet it (2-way) but the offered hand is quickly withdrawn. The server waits for the hand to come back until it ‘times-out’ and then the cycle repeats millions of times. The 3-way handshake is never established and all other connections are refused while this is happening.

USB Auto-Run Attacks:

By default, Windows runs any executable, program, or script on a USB drive the second it is inserted into any computer or laptop. This means that anyone* with unauthorized code, like a virus or …

Slow Computer? Maybe It's Time For a Registry Scan

Posted on Posted in computer, internet

If your computer is running slowly, then it might time to think about performing a registry scan. These are widely claimed to be able to fix many different errors on your computer and speed it up. But how do you perform one of these scans and can they really boost the speed of your PC?

A registry scan is the term used to describe the process you take to clean out the 'registry databsae'. This database is the central storage facility for Windows and is where your PC keeps information ranging from your latest emails to your desktop wallpaper. A lot of people recommend cleaning out the registry as a good way to speed up your PC.

Registry scans can speed up your computer considering thanks to the way in which they work. To perform a 'registry scan' you should use a registry cleaner tool, which is a software program that scans the entire registry database and removes and damaged or corrupt settings that are inside it. The way in which one of these tools speeds up your PC is to scan through the entire registry database and remove any of the damaged or corrupt files that are slowing it down. This will allow Windows to read all the settings it needs in a much faster time, allowing your computer to run faster – like it did when it was new.

Using a registry scan is a good way to make your PC run faster as it acts like a "detox" for Windows. Unlike other operating systems, Windows relies mainly on the registry to help it remember various different files … which means that if you can get a registry tool to fix all the problems that it has inside the database, it will make your PC run much faster and more reliably. To use a registry cleaner to speed up your PC, you should first download one from the Internet. There are many different sites which offer these tools, allowing you to find one which is going to remove a lot of errors from your system.

After you've downloaded a registry scanner, install it and it will start to scan yor PC. You can then see all the errors that it is finding. Each error can cause your PC to run as much as 30 seconds slower – as your PC has to take longer to read through the details that the setting needs. This means that if you can get a registry tool that can fix the largest number of errors on your system, it should be able to run as fast as it did when it was new. And that's why so many people recommend using a registry scan to speed up your PC. It does not work all the time though – and before committing to fix any registry errors, you should only allow it to fix the errors on your PC if there are 300+ on there. …

How to Completely Delete Files From a Computer

Posted on Posted in computer, technology

Most people do not think about it, but when they delete a file from their computer, it is not destroyed. The computer deletes certain key information about the physical location of the file from the disk directory on the hard drive. The file is still sitting there on the disk and can be recovered by someone with the knowledge and the right equipment. Knowing this, one may be asking about now, “is there a way to completely delete files from a computer?” The answer is yes.

One method of deleting files in a way that makes it impossible to recover them is using a large magnet to degauss the hard drive. This realigns the magnetic fields on the disk and effectively erases every scrap of data that was ever stored there. The drawback to this method is that the disk is completely erased, including system files and operating systems.

Today, it is possible to purchase software that is capable of overwriting an entire disk to cover the data with random number sequences that mean nothing. One pass of this software will normally render files impossible to retrieve for civilians. Government agencies and police forces can still get the data off the disk. It takes up to seven passes with this type of software to completely overwrite all files and make them irretrievable. This method also overwrites the entire disk, destroying data that may be valuable or wanted to be kept.

The newest technology involves a file shredder program that randomizes the data in the deleted files at the time of deletion. These are still physically present on the disk, but the data is so scrambled that no computer is able to make sense of it. This method allows one to completely delete files from a computer without completely erasing the entire disk.…

The Difference Between AutoCAD and SolidWorks

Posted on Posted in computer, programming

SolidWorks is what we call a “parametric” solid modeller used for 3-D design. Parametric means that the dimensions can have relationships between one another and can be changed at any point during the design process to automatically alter the solid part and any related documentation (blueprint). AutoCAD, however, is primarily a 2-D design tool with some, but limited 3-D capabilities. It is very simple compared to any parametric solid modeller (although 3D is improved in AutoCAD 2007). Autodesk (the manufacturer of AutoCAD) makes a product that is nearly identical to SolidWorks, called Inventor, which is a parametric program for design of solid parts and assemblies.

SolidWorks is a 3D mechanical CAD (computer-aided design) program that runs on Microsoft Windows. SolidWorks files use the Microsoft Structured storage file format. This means that there is various files embedded within each SLDDRW (drawing files), SLDPRT (part files), SLDASM (assembly files), with preview bitmaps and metadata sub-files. Various third-party tools can be used to extract these sub-files, although the sub-files in many cases use proprietary binary file formats. SolidWorks is a parasolid-based solid modeller, and utilizes a parametric feature-based approach to create models and assemblies. Parameters refer to restrictions which values determine the shape or geometry of the model. Parameters can be either numeric, such as line lengths or circle diameters, or geometric, such as tangent, parallel, concentric, horizontal or vertical. Numeric parameters can be associated with each other through the use of relations, which allows them to capture design intent.

AutoCAD is, just like SolidWorks, a Computer Aided Design software application for 2-D and 3-D design and drafting. AutoCAD was one of the first CAD programs to run on personal or home computers, notably the IBM personal computer. At that time, most other CAD programs ran on mainframe computers or mini-computers that were connected to a graphics computer terminal for each user. Early releases of AutoCAD used basic entities such as lines, poly-lines, circles, arcs, and text to ultimately construct more complex objects. AutoCAD has since started to support custom objects through its C++ Application Programming Interface (API).

Modern AutoCAD includes a full set of basic solid modelling and 3-D tools. With the release of AutoCAD 2007 improved 3D modelling saw the light, which means better navigation when working in three dimensions. It also became easier to edit 3-D models. The mental ray engine was included in rendering and thus it was now possible to do quality renderings. AutoCAD 2010 introduced parametric functionality and network modelling. At this moment, AutoCAD only runs under Microsoft Windows operating systems. It is available in 32-bit and 64-bit versions. AutoCAD can run on an emulator or compatibility layer like VM-ware Workstation or Wine, although various performance issues can arise if you work with 3-D objects or large drawings.

Choosing a system that works for you depends solely on the type of work you want to do. Many experts say that SolidWorks is more effective when working on 3 dimensional designs and that AutoCAD is the way to …

3 Steps To Better Computer Security Solution

Posted on Posted in computer

There are dozens of things that you can do to protect your computer. People sell so many software packages and information products you may not be able to get a handle on all of it. Have you surprised to yourself what the basics are so that you can protect your identity and your data and so that you no longer have to worry?

I am not sure if we will ever get to a point that a computer security solution is perfect and we never have to worry but we can get to a point of an increased security posture. That just means that we can take a few steps to help protect ourselves against the not so nice people in the world.

    First if you have a computer you should turn on a local firewall.

You may say, I am working behind one of those routers you can purchase from the electronics store, I am safe. There is a term in the field that is called defense in depth. There are many takes on what this actually means and how to implement it but I will be the first to tell you every extra security precaution you can take will be helpful in the effort to protect your identity and your data.

Each layer of defense will add to your protection. You may have a router but go ahead and turn on that software firewall that comes with your operating system too. Learn more about your computer so that you can be proactive. You never know when you might travel with that laptop and your software firewall saves you from an intrusion. Just be cautious. Most people lock their doors at night before they go to bed or when they leave for work in the morning. Do not forget to lock the doors on your computer.

    Second, you may consider installing a well-established anti-virus product.

There are many packages on the market. Some you can get for free and others you can pay for. You need to determine your level of knowledge and how much support you may require.

There are many anti-virus vendors that are free that have been certified and protect your systems just as well as the pay for kind. The main difference is that you may get better support from the pay for kind. You may end up supporting the free kind on your own and having to do research on the net for answers. This is truly your call and should be congruent to your level of computer knowledge.

Anti-virus software should be a must. It has saved my system many times as well as friends of mine. I had a buddy that downloaded pictures form a digital camera that was infected with a virus. They can be anywhere. This is just another layer of defense you should consider in your quest to protect your identity and your data.

    Third, you should consider backing up your system regularly.

I am not talking about once …

What Does the Word Website Designer Stand For?

Posted on Posted in computer, internet, website

Today anyone seems to call themselves web designer just because the learned to create a web site.

Is it traditional graphic design involved or is it just experts on programs like Flash, Dreamweaver, etc. who call themselves designers?

One guy looking for work told me he had a web design education and when I looked at his work it was like 5 pages crap made in FrontPage!

For me as an art director and graphic designer it all looks a bit strange. I have spent years in art- and advertising classes, over 30 years in the advertising business in Sweden and Spain and I'm still not sure I can use that title. Even if I have designed hundreds of websites last 10 years.

So be aware when you are looking for help, with internet anyone seems to be whatever they like and advertise their services, trust them or not. You will never know for sure.

Today I saw the following ad in a local magazine: "We design web sites for 130EUR". That guy must be something of a superman. Or is the education these days so fantastic that you can learn it all in a few years?

The "Graphic design" education is just a small part in building your web site.

The natural way was (back in the 80: s in Stockholm) that your advertising agency produced your website and designed it so it fit your company's profile. A few years later a lot of digital production companies started, but still with people educated in the advertising business.

Short after that anyone with money could buy a computer, copy machines and some color printers and start a copy shop without any education in advertising. Unfortunately they are after a while also offered help in layout and design.

That's where we are today. Anyone with a computer can offer you anything online.

It's up to you to find out who they are. …
