Basic Security for Computers and Other Electronic Devices

Basic Security for Computers and Other Electronic Devices

The software on computers and other electronic devices must be set up and maintained to help protect the data and the computer. Basic Security for Computers and Other Electronic Devices requires:

• Authentication (Password, Pass phrase or other strong authentication)
• Configuration
• Firewall
• Use of Flash drives
• Anti-Virus Protection
• Security Patches

Authentication (Password, Pass phrase, M Key or other strong authentication):

• Password or pass phrase must be used for all devices and software supporting authentication, unless using a higher level of authentication (e.g. M Key).
• Must be eight or more characters long. Longer passwords are better.
• Must be periodically changed as required by each system, but at least annually.
• Must contain a minimum of three types of characters (lower case, upper case letters, numbers, special characters).
• Unique user accounts and  passwords must be managed to a security level appropriate for the system, based on the data stored or accessed through them.
• A password is required upon resuming use from an inactive state (Hibernation, Sleep, Screen Saver) to prevent unauthorized access when unattended.
• Password protected Screen Saver must activate within a maximum of 30 minutes of inactivity.
• The desktop/laptop computers must be logged off when not in use during non-work hours.

Configuration:

There should be restrictions in accessing the computer. The account should be divided with the user and the administrative rights.

• Access to an account with administrative level privileges for desktop/laptops must only be provided to the senior level. Such administrative access must be approved annually in writing by the supervisor. Use of the administrative level account must be limited to those actions which require administrative access.
• A separate standard user level account must be used for daily tasks such as email and web surfing.

 Use of Firewall:

• A firewall puts a protective barrier between your computer and the Internet. Turning it off for even a minute increases the risk that your PC will be infected with malware.
• A software firewall, hardware firewall or other network filtering (e.g. port or IP address filtering) technology must be used to help protect the computer/device while on the network.
• Desktops and laptops should use the operating systems built-in or other software firewall.

 Use flash drives cautiously:

Minimize the chance that you'll infect your computer with malware:

• Don't put an unknown flash (or thumb) drive into your PC.
• Hold down the SHIFT key when you insert the drive into your computer. If you forget to do this, click   in the upper-right corner to close any flash drive-related pop-up windows.
• Don't open any files on your drive that you have not expected to see.

 Anti-Virus Protection:

Computers are required to maintain and use an up-to-date version of anti-virus software (or virus filtering software for Unix). Other electronic devices are required to use anti-virus protection, if available.

Minimum Configuration for Anti-Virus Software should be:

• Live Update should be enabled
• Live Update Schedule Frequency should be on daily basis.
• File System Real Time Protection is enabled 

Security Patches:

Operating systems and application programs have periodic security patches released by the vendor that need to be installed. Installation of newer versions of the operating system or application program may be needed.

• Software applications, whether installed by a user with access to the administrative level privileges or technical support staff, must be maintained.
• Patching for designated high risk software applications is required as soon as possible but not more than 30 days after availability from vendor.
• All other operating system and application program security patches/updates must be installed as soon as possible but not more than 30 days after release by the vendor.
• Desktop and laptop computers must have automatic updates enabled  for the operating system.

Some free protections are available to secure your computer against malware:

Build up your computer's defenses:

Install antivirus and anti spyware programs from a trusted source.

• Never download anything in response to a warning from a program you didn't install or don't recognize that claims it will protect your PC or offers to remove viruses. It is highly likely to do the opposite.
• Get reputable anti-malware programs from a vendor you trust.
• Windows 8 includes antivirus protection called Windows Defender. It’s turned on by default.
• If your computer is not running Windows 8, download Microsoft Security Essentials for free.
• Choose security software that is compatible with Windows 7.

Update software regularly:

Cyber criminals are endlessly inventive in their efforts to exploit vulnerabilities in software, and many software companies work tirelessly to combat these threats. That is why you should:

• Regularly install updates for all your software—antivirus and anti spyware programs, browsers (like Windows Internet Explorer), operating systems (like Windows), and word processing and other programs.
• Subscribe to automatic software updates whenever they are offered—for example, you can automatically update all Microsoft software. Windows 8 and Windows 7 turn on automatic updating during installation.
• Uninstall software that you don't use. You can remove it using Windows Control Panel.

Use strong passwords and keep them secret:

• Strong passwords are at least 14 characters long and include a combination of letters, numbers, and symbols. Learn more about how to create them.
• Don't share passwords with anyone.
• Don’t use the same password on all sites. If it is stolen, all the information it protects is at risk.
• Create different strong passwords for the router and the wireless key of your wireless connection at home. Find out how from the company that provides your router.
• Use our password checker.

Don't be tricked into downloading malware:

• Be cautious in  opening an attachment or clicking a link in an email, instant message, or post on social networks (like Facebook)—even if you know the sender. Call to ask if a friend sent it; if not, delete it or close the IM window.
• Avoid clicking Agree, OK, or I accept in banner ads, in unexpected pop-up windows with warnings or offers to remove spyware or viruses, or on websites that may not seem legitimate.
• Instead, press CTRL + F4 on your keyboard to close the window.
• If the window doesn't close, press ALT + F4 on your keyboard to close the browser. If asked, close all tabs and don’t save any tabs for the next time you start the browser.
• Only download software from websites you trust. Be cautious of "free" offers of music, games, videos, and the like. They are notorious for including malware in the download.
• Take advantage of technology—such as Windows Smart Screen in Windows 8—designed to help protect you from new virus.

Hide and convert exe into jpeg

How to hide and convert exe into jpeg ?

1. Firstly, create a new folder and make sure that the options ‘show hidden files’ is checked and ‘hide extensions for known file types’ is unchecked. Basically what u need is to see hidden files and see the extension of all your files on your pc.
2. Paste a copy of your server on the new created folder. let’s say it’s called server.exe (that’s why you need the extension of files showing, cause you need to see it to change it).
3. Now you’re going to rename this server.exe to whatever you want, let’s say for example picture.jpeg
4. Windows is going to warn you if you really want to change this extension from exe to jpeg, click YES.
5. Now create a shortcut of this picture.jpeg in the same folder.
6. Now that you have a shortcut, rename it to whatever you want, for example, me.jpeg.
7. Go to properties (on file me.jpeg) and now you need to do some changes there.
8. First of all delete all the text on field START IN and leave it empty.
9. Then on field TARGET you need to write the path to open the other file (the server renamed picture.jpeg) so u
   have to write this: C:WINDOWSsystem32cmd.exe /c picture.jpeg
10. The last field, c picture.jpeg is always the name of the first file. If you called the first file soccer.avi you gotta write C:WINDOWSsystem32cmd.exe /c soccer.avi got it?
11. So what you’re doing is when someone clicks on me.jpeg, a cmd will execute the other file picture.jpeg and the
12. server will run.
13. On that file me.jpeg (shortcut), go to properties and you have an option to change the icon. click that and a
    new window will pop up and u have to write this: %SystemRoot%system32SHELL32.dll . Then press OK.
14. You can set the properties HIDDEN for the first file (picture.jpeg) if you think it’s better to get a connection
    from someone.
15. But don’t forget one thing, these 2 files must always be together in the same folder and to get connected
    to someone they must click on the shortcut created not on the first file. So rename the files to whatever you want considering the person and the knowledge they have on this matter.
16. For me for example I always want the shortcut showing first so can be the first file to be opened.
    So I rename the server to picture2.jpeg and the shortcut to picture 1.jpeg. This way the shortcut will show up first.
17. If you set hidden properties to the server (picture.jpeg) then u don’t have to bother with this detail but I’m warning you, the hidden file will always show up inside of a zip file or rar. So the best way to send these files together to someone is compress them into zip or rar. I
18. Inside the RAR or ZIP file you can see the files properties and even after all this work you can see that the
    shortcut is recognized like a shortcut but hopefully the person you sent this too doesn’t know that and is going to open it.

Improve Your Website's Google Ranking

How to Improve Your Website's Google Ranking

 

Simple Tips to Improve Your Website’s Rank:

Keyword Phrases:

A keyword phrase are the words that you think someone is most likely to put into a search engine to find your content. They should appear in your content. Don't overdo it just use natural language, words that humans are most likely to use when searching for a page about your topic. Clear writing is both easier to search and easier to read.You can also check Google Trends to see if one phrase is starting to gain popularity. Try to stick to one subject per page, and stick to one keyword phrase per page.

Density

One of the things Google looks for the density of the keyword used per page means, how often the keyword occurs. Use natural phrasing. Don't try to trick the search engine by repeating the same word over and over or making text "invisible". It doesn't work. In fact, this type of behavior even gets your website banned.Give a strong opening paragraph that says what your page is actually about. This is just good practice, but it may help search engines find your page, too.

Name Your Pages:

Give your pages a descriptive name with the <title> attribute. Google often displays search results as a link using the Web page's title. A link called 'untitled' isn't enticing, and nobody is going to click on it. When appropriate, use the page's keyword phrase in the title.

Links:

One of the biggest factors Google looks at is the hyperlink. Google looks at both links to and from your website.Google looks at the words you use in links to help determine the content of your page. Use links within web pages as a way to emphasize keywords you are explaining (title).Links from other websites to your website are used to determine Page Rank also called as (exchanging text links with other relevant websites).

Social Networking:

Social networking sites can be a good way to promote a site, but it is unclear how much it will affect your rank directly. Google+ promotion may have the most impact. That said, you may find that a great deal of your traffic comes from social networks, so be sure to make your content social friendly. Add images and give your content interesting titles.

Make Your Graphics Search Friendly:

Give your images <alt> attributes. Not only does it make your website more accessible but also gives you another chance to place your keywords where Google can see them.

Good Design Is Popular Design:

In the end, strong, well organized pages are pages that Google tends to rank higher. They're also pages that tend to become more popular, which means Google will rank them even higher. Keep good design in mind as you go, and much of the SEO will design itself.

Pool your votes:

www.techiego.com and http://techiego.com  are seen as different pages by search engines. This can result in any links that you receive being diluted between the two pages. The solution to this problem is to tell Google that you want all the votes from www.techiego.com to be counted towards http://techiego.com. This can be easily implemented by using a permanent (known as a 301) redirect from one of the pages to the other.

Offer discounts:

Everyone loves a good deal and clubs and organizations love to promote such benefits to their members. Put such thing in your site if it allows you to do so. Offering an exclusive discount to a club or organization is a highly effective way of receiving a link.

Locate references without links:

Look for web pages that mention your business or website. Without a link back to your site, use Google Alerts to create an automated notification, so that anytime a website mentions your business, you will receive an e-mail. You can then get in touch and ask them to provide a link back to your website.

Target the right keywords:

One of the biggest mistakes that websites make is targeting the wrong keywords. Take the time to analyze the keywords that produce conversions and make you money. One way to do this is to have analytic software, like Google Analytics, installed on your website so that you can see how visitors are interacting and finding your site. Google Analytics is free and simple to install. After signing up for an account, you are given a JavaScript code that is placed on every page of your site. After verifying the code has been installed correctly, you should immediately start receiving insights into how visitors are arriving at your website, including which keywords that are causing them to engage.

Develop Android Application

The tutorial of “How to Develop Android Application” is based on API Level 17 and Android 4.2 (Jelly Bean).

Develop Android Application:

1. What do you Need:

• Knowledge of Basic XML
• Knowledge of Basic Java
• Knowledge of Basic Eclipse

2. Prerequisites:

• First you need the Android SDK and IDE. (Android offers a special bundle for that: Android SDK Bundle)
• Download the Android SDK Bundle then unzip it and run as “SDK Manager.exe”.
• Start the Eclipse

3. Create a Android Virtual Machine (dalvik):

On your computer you can create and run a virtual android machine to run, test and debug your application. Later to this virtual machine you can deploy your application.

• At the navigation toolbar click on “Windows”.
• Open “Android Virtual Device Manager”.

Create a “New” Virtual Device:

Be sure that “Use Host GPU” is enabled. To use the Host GPU this allows the AVD and this helps you to render the AVD as much faster.

After that you can start the AVD:

4. Create a New Project:

• First open a “File”.
• Then select “New”
• New Android Application Project window is open.

For your project chose a new and click to the next:

Now Configure a Project and click to the next:

Now Configure Launcher Icon window is open:

Here, you can choose a launcher Icon that will be displayed on your mobile phone and click to the next.

Create a New Activity window is open and click to the next.

New window is open to configure your Activity and then click to the Finish.

Eclipse looks similar to that after finishing it.

 

5. Implement the Look and Feel:

To “/res/layout/” navigate in the package explorer and open “activity_main.xml”

Right click on the “Hello World” and then delete it.

5.1 Create an static Attributes:

Select “/res/values/strings.xml”

 

“Add” a new entry

Select the color entry and then press ok and after that set the following attributes:

Add a few more String (!) attributes:

Name/value:”miles” /”to Miles”

Name/value:”kmh” /”to km/h”

Name/value:”calc” / “Calculate”

Switch from “Resource” to “string.xml” and make sure that your code is look similar to that snippet:

view plaincopy to clipboardprint?

<resources> 

<string name="app_name">TutorialApplication</string> 

<string name="action_settings">Settings</string> 

<string name="hello_world">Hello world!</string> 

<color name="myColor">#eeeeee</color> 

<string name="miles">to Miles</string> 

<string name="kmh">to km/h</string> 

<string name="calc">Calculate</string> 

</resources> 

 5.2 Add Views

Select “/res/layout/activity_main.xml”

Via double-click, open Android editor.

There are two possibilities. Via drag & drop you can create a new view or edit the XML source code. In this tutorial via drag & drop we can add the views.

Now, let’s start building our app. At first for the output, we have to add a “Text Field”.

To your application drag this field.

Select the section of “Form Widget” and to your App drag a Radio Group and make sure that the Radio Group has two Radio Buttons. Finally you can add a normal button.

 

Switch from “Graphical Layout” to “activity_main.xml” and make sure that your code looks similar to that:

view plaincopy to clipboardprint?

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 

xmlns:tools="http://schemas.android.com/tools" 

android:layout_width="match_parent" 

android:layout_height="match_parent" 

android:paddingBottom="@dimen/activity_vertical_margin" 

android:paddingLeft="@dimen/activity_horizontal_margin" 

android:paddingRight="@dimen/activity_horizontal_margin" 

android:paddingTop="@dimen/activity_vertical_margin" 

tools:context=".MainActivity" > 

<EditText 

android:id="@+id/editText1" 

android:layout_width="wrap_content" 

android:layout_height="wrap_content" 

android:layout_alignParentLeft="true" 

android:layout_alignParentTop="true" 

android:layout_marginLeft="24dp" 

android:layout_marginTop="31dp" 

android:ems="10" 

android:inputType="numberDecimal|numberSigned" > 

<requestFocus /> 

</EditText> 

<RadioGroup 

android:id="@+id/radioGroup1" 

android:layout_width="wrap_content" 

android:layout_height="wrap_content" 

android:layout_alignLeft="@+id/editText1" 

android:layout_below="@+id/editText1" 

android:layout_marginTop="28dp" > 

<RadioButton 

android:id="@+id/radio0" 

android:layout_width="wrap_content" 

android:layout_height="wrap_content" 

android:checked="true" 

android:text="RadioButton" /> 

<RadioButton 

android:id="@+id/radio1" 

android:layout_width="wrap_content" 

android:layout_height="wrap_content" 

android:text="RadioButton" /> 

</RadioGroup> 

<Button 

android:id="@+id/button1" 

android:layout_width="wrap_content" 

android:layout_height="wrap_content" 

android:layout_alignLeft="@+id/radioGroup1" 

android:layout_centerVertical="true" 

android:text="Button" /> 

</RelativeLayout> 

 5.3 Edit the view properties

Via right-click on the view or via XML, you can edit the properties of Views.

Navigate to “res/layout/” and open the Graphical Layout of your “activity_main.xml”

Right-click on the first Radio Button and open the “Edit Text”

To the second Radio Button, assign the miles property

For the first Radio Button set the “Checked” property (Other Properties -> inherited from compound button -> checked -> true)  

For the Text Field to “number Signed” and number Decimal” set the “Input type” property.

To the Button assign “calc” and for the “on Click” property set “calculate” (Other Properties -> inherited from view -> on Click)

Set Background-Color (Right-click on an empty space on your Application -> Edit Background)

After that change the Background should be #eeeeee! To see the difference it can be difficult.

6. Implement the Logic

After we implement the Frontend-View we have to implement the logical part with Java!

Switch to “src/com.example.tutorialapplication/” and open “MainActivity.java”

view plaincopy to clipboardprint?

package com.example.tutorialapplication; 

import android.os.Bundle; 

import android.app.Activity; 

import android.view.Menu; 

import android.view.View; 

import android.widget.EditText; 

import android.widget.RadioButton; 

import android.widget.Toast; 

public class MainActivity extends Activity { 

    // public var 

    private EditText text; 

    // default func 

    @Override 

    protected void onCreate(Bundle savedInstanceState) { 

        super.onCreate(savedInstanceState); 

        setContentView(R.layout.activity_main); 

        // findViewById = Finds a view that was identified by the id attribute 

        // from the XML that was processed in onCreate(Bundle). 

        // (EditText) = typecast 

        text = (EditText) findViewById(R.id.editText1); 

    } 

    // default func 

    @Override 

    public boolean onCreateOptionsMenu(Menu menu) { 

        // Inflate the menu; this adds items to the action bar if it is present. 

        getMenuInflater().inflate(R.menu.main, menu); 

        return true; 

    } 

    /*

     * Will be executed by clicking on the calculate button because we assigned

     * "calculate" to the "onClick" Property!

     */ 

    public void calculate(View view) { 

        RadioButton mileButton = (RadioButton) findViewById(R.id.radio0); 

        RadioButton kmhButton = (RadioButton) findViewById(R.id.radio1); 

        // if the text field is empty show the message "enter a valid number" 

        if (text.getText().length() == 0) { 

            // Toast = focused floating view that will be shown over the main 

            // application 

            Toast.makeText(this, "enter a valid number", Toast.LENGTH_LONG) 

                    .show(); 

        } else { 

            //parse input Value from Text Field 

            double inputValue = Double.parseDouble(text.getText().toString()); 

            // convert to... 

            if (mileButton.isChecked()) { 

                text.setText(String.valueOf(convertToMiles(inputValue))); 

                // uncheck "to miles" Button 

                mileButton.setChecked(false); 

                // check "to km/h" Button 

                kmhButton.setChecked(true); 

            } else { /* if kmhButton isChecked() */ 

                text.setText(String.valueOf(convertToKmh(inputValue))); 

                // uncheck "to km/h" Button 

                kmhButton.setChecked(false); 

                // check "to miles" Button 

                mileButton.setChecked(true); 

            } 

        } 

    } 

    private double convertToMiles(double inputValue) { 

        // convert km/h to miles 

        return (inputValue * 1.609344); 

    } 

    private double convertToKmh(double inputValue) { 

        // convert miles to km/h 

        return (inputValue * 0.621372); 

    } 

}
