Keeping an Android smartphone and tablet secure requires a lot more than adding a PIN or password lock. Any malicious app download or connection to an unsecure wireless network can not only jeopardize your online privacy, but also increase the risk of loss/theft of your confidential data.

Given below are some tips that can help you to improve the security of your Android device:

Lock all the apps and media

In addition to the screen lock, you can add an extra layer of protection by restricting access to the apps and media. This is particularly important for the apps that hold your private and sensitive information, such as social networking, email, online banking etc. This will prevent anyone from using your Android device, specifically if it has been lost or stolen. Make sure you select different PIN and password combinations for each app.

Download apps only from trusted sources

Your device’s default settings restrict downloading apps from any other source except Google Play Store. You should not change these settings as it may put your device’s security at risk. All apps on the Play Store are scanned for malware and other potential threat, which makes them safe to use. If you want to download third party applications, ascertain that you check their reliability and reviews before doing so. You should also go through the app permissions carefully. Do not install an app that seems to ask for permissions that are not required for its functioning.

Get virus and malware protection

Android, being open source software, is at a higher risk of hacking attacks and security breaches. Simply clicking on a link or downloading a file can infect your device with viruses and malware. Therefore, it is recommended that you download an anti-virus and anti-malware software. Run frequent scans to identify and remove any potentially harmful files from your device.

Use Android device manager

Android device manager can be really helpful in case your phone is lost or stolen. It allows you to lock your device and erase all the data stored on it, from a remote location. You can also track the location of the device using GPS technology. Once enabled, Android device manager works even after someone uninstalls the app from your device.

Bloatware, also known as crapware, refers to the multiple pre-installed applications and software programs on a computer system that do not serve any important function. It usually consumes a lot of RAM and storage space on the hard disk, causing the system to work slowly. Certain types of bloatware are easy to detect, i.e. they may be present as a desktop icon or a start menu shortcut. However, some of them may remain unidentified and just clutter the computer system.

Types Of Bloatware

Trialware: These are the trial versions of software that are installed for a specific period of time, usually a week or a month. They mainly include anti-virus and anti-malware programs, which need to be purchased if one wants to use them after the trial period is over. In most cases, trialware can be easily identified and uninstalled.

Adware: This is one of the most annoying types of trialware that pops up unwanted ads on the computer screen. It can not only hamper your internet browsing experience, but also slow down your PC and make it vulnerable to various hacking attacks.

Utility Applications: Computer manufacturers may install certain utility applications that allow users to troubleshoot any hardware/software problems, update programs, install third party browser toolbars etc. The purpose served by these applications is similar to the in-built programs of the operating system. Add-on software to create videos, edit photos, play DVDs and other media or write CDs also come under the category of bloatware.

Tips To Remove Bloatware From Computer System

One of the best ways to completely uninstall bloatware from your computer is to wipe off the hard drive and re-install the operating system. This will delete all software installed on the system and you can install the ones that are required. If you simply use the system’s recovery utility, it will install all the applications again, including the bloatware.

Another option is to perform the uninstallation process manually from the control panel. Identify and delete the software that you do not use. However, it may leave certain associated files or programs on your computer. For applications that are operated by the Windows registry, it is recommended that you perform a complete uninstall from the software vendor’s website.

Every business firm implements stringent security policies to mitigate the risk of a data breach. However, as hackers are becoming more sophisticated in the use of advanced tools and technologies, ensuring complete security against an attack may not be possible. It is important that you formulate an incident response plan that specifies what needs to be done in the event of a data breach in order to minimize its impact on the business operations.

Listed below are the five key steps that you need to take if your organization witnesses a security breach:

Conduct Complete Investigation

Clear thinking and immediate action is important to deal with a security breach in an efficient manner. Analyze when the attack occurred, how the hackers got access to the network, which systems have been compromised as well as what information has been leaked. This will give you an idea about the steps required to reduce the impact of the incident.

Ensure Containment

All the potential causes of the security breach should be controlled with immediate effect. Install software updates and patches to make sure your network does not remain vulnerable for a long period. Change the password for all the compromised accounts as well as those that use the same log in credentials. Restrict the infected computer systems from accessing the corporate network.

Communication

There should be constant communication between the company management and incident response team. Providing frequent updates to the customers, regulatory authorities or third party investigation agencies may also be necessary, depending upon the extent and nature of the data breach. In order to avoid any delays or miscommunication, lay out a specified medium through which information should be conveyed.

Implement And Test The Security Fix

Once the vulnerability has been identified and fixed, you must ensure that you have completely recovered from the breach. The IT security team should review the server logs and network traffic. You can also consider executing a penetration test to identify any unpatched security flaws.

Prevention Of Future Breaches

Lastly, you should thoroughly audit your data security practices to determine if there is a scope for improvement. Provide training to your employees on the best practices to keep their official accounts and data safe. Regularly re-evaluate your security policies to identify any modifications or additions required to stay protected against attacks.

Securing Your FTP Server

File transfer protocol (FTP) has become one of the most popular and convenient ways of sharing data within a network. Considering its extensive usage, FTP security has become an important concern for the IT professionals. A poorly configured server can act as a critical flaw in the cyber security of an organization.

Given below are some tips that you should follow to secure your FTP server:

Define user accounts and permissions

Each user on the FTP server should have a separate account and login directory. This will help to ensure that the files are accessed only by the authorized users. In case you want to create directories that can be shared by multiple users, you can explicitly state the permissions for each of them. Also, access should be allowed according to the specific duties to be performed by the employees. For instance, if one needs to simply read a file, permissions to share, modify or delete it should be disabled.

Enable logs

When you enable logs in your FTP server, you can have a complete record of the IP addresses and users who accessed the server. Maintaining a log will help you to identify the traffic patterns, unauthorized login attempts and any potential security threat.

Limit the number of incorrect logins

Make sure you restrict the number of invalid logins that a user can make. After the set limit has exceeded, the account gets locked and needs to be activated again. This reduces the likelihood of a brute force attack, in which the hackers gain access to a network by guessing multiple password combinations. Ideally, you should set the permissible login attempts between 3 to 5.

Enforce password compliance

Weak passwords are often the biggest loopholes that allow the hackers to access the FTP server. You should enforce strong password policies and make sure that all the users comply with it. The password should consist of 8 to 10 characters comprising of uppercase and owe case letters as well as alphanumeric characters. You can also implement a policy that requires users to change their passwords after a set period of time.

Cyberstalking is a common type of cyber crime that involves using electronic means of communication, such as IMs, emails or social media, to stalk the victim. The stalker may send threatening messages, make false accusations, spy the victim’s internet activities, steal his identity or simply make unwanted advances to stay in contact.

Given here are some tips that should be followed to protect yourself against cyberstalking:

Be Careful While Sharing Information Online

It is important to be cautious when you post anything on social media or share information through emails or IMs. It is very easy for the hackers to gather details about you such as name, residence, places of interests, friends and likes/dislikes.

Google Yourself

Search your name on Google to see what results are being displayed. It is quite possible that hackers have created fake profiles in your name. You can also search your phone number to detect any unwanted information about you. Delete or report all the incorrect or unauthorized information you find about yourself on the internet.

Password Protect All Accounts

Create strong passwords for all your online accounts specifically online banking, email and social networking profiles. The security questions you choose should be complex so that the correct answers cannot be guessed by the stalker. Avoid using your name, date of birth, phone number or other such trivial details in your password.

Stay Vigilant

In some cases, the cyberstalker may attach a web-enabled device to the victim’s computer system to monitor his activities. A software program or application may also be installed that transmits all your sensitive information to the stalker. Therefore, make sure you stay vigilant and perform a regular check to identify any such threats. Always log out of the computer system and lock the screen when you are away.

Review Your Privacy Settings

Social networking websites constantly keep on changing their privacy policies so you should keep a check on your account settings. Limit the number of people with whom you are sharing your information. You can even block some people from seeing your posts or photos. Accept friend requests from only those people whom you personally know and trust.
