Configuring New Laptop

PROCESSOR (CPU)

Intel the world’s largest semi conductor maker has begun the process of transitioning into a quad core line of processors. Their range is branded as Core i3, i5 and i7. If you are hunting for a bargain then you could choose its older Core 2 models, but you would be better off sticking to its latest range.

You could also consider a processor from Intel rival AMD which has a compelling range of products branded as Turion II and Athlon II. If you are a budget shopper then these processes are well worth considering and will serve the purpose for most tasks. The big difference between processors made by AMD is they are simply not as fast as those made by Intel and they tend to act as a drain on battery life.

The most important task is working out exactly how much processing power you need. In general the Core i3 or i5 are suitable for most people. If however you do a lot of video editing then you are going to need a more powerful processor. Gamers in particular believe they need a powerful processor but in practice can actually get away with a slower chip.

Quad core chips still cost a lot and also tend to drain battery life quite quickly. You can identify a quad core chip by the Q denoted next to the machine’s model number. If you use your laptop as your main machine, and not taking it out on the road, or you are a gamer or video editor, the quad chip case becomes more compelling.

The decision over processor gets trickier when you are ordering a custom laptop from a manufacturer. You should as a rule avoid the most expensive chipsets on offer and go for the second or third least costliest chips. The increase in price is usually proportional to performance. You should not spend more than $150 upgrading a processor. If you are simply surfing the internet or word processing, even a dual core processor is more than adequate.

MEMORY (RAM)

4GB RAM is the standard memory offered by most manufacturers even on low end laptops and that is really all you need. Starting prices for a laptop with 4GB RAM are just under $500. In the past manufacturers used to make consumers pay through the nose when they upgraded the memory whilst custom ordering. More recently, this practice seems to have changed, and only Apple really still does this.

If upgrading your memory to 4GB costs you less than $90, which is what it costs separately, then you should definitely upgrade. Upgrading beyond 4GB is going to be expensive, and the only real reason to do it is if you are video editing, and even then it’s still not absolutely necessary when you compare it against the expense. For a desktop, spending an additional $100 is no big deal, but for a laptop where it is going to cost you an additional $300 for 8GB, it’s simply not worth it unless your laptop is your primary video editing device.

Choose Good Mobile Applications Developer

These are some the most chanted names that brought mobile application development into the mainstream. It would not be the wrong to say that it has become a well-known profession that is too offering the broader possibilities to earn in dollars. In this way, it is seen among the most beneficial fields that have great scope to make a flourishing career.

In it meaning, mobile app development is defined as a process that comprises the development of application software for low-power handheld devices like enterprise digital assistants, personal digital assistants, and mobile phones. But, everyone does not go along with this task as there is a need to appoint a mobile app developer.

Sometimes these applications are pre-installed on mobile gadgets during their manufacturing, but it is not always the same. This is a kind of development that revolves around so many tools and tactics for which a developer has to keep himself abreast with.

For instance, a wide range of screen sizes is available for mobile devices, so it becomes essential for a programmer to appear with apps that are highly compatible with varied screen sizes. As there is an intense competition regarding hardware specifications and configurations, so he has to work with the changed format on different platforms.

Whatever the field of app development let it be entertainment, gaming, social networking, etc., a mobile app developer has to ensure the high security of the mobile devices.

He should appear with such solutions that security of these devices must not be breached at any cost. As well, he has to keep such factors away that might be threatening for data, app or its functionality. Combating with the security breaching elements, he also needs to appear with mobile applications that are high performing, rich in features and unique.

To stay away from such obstacles, the best suggestions for him to remain updated with every new release and versions of mobile phones and their applications. Above all, never forget the specified tastes and preferences of the end-user and created application must be user-friendly otherwise the success of apps is not guaranteed.

Several platforms are available in the market in the direction of making incredible mobile applications. The broad gamut of these tools comprises programming languages, emulators, cross-platform deployment, debuggers and much more.

Now, it is up to the mobile applications developer that how he makes the best use of these platforms and appears with something matchless. It is good that the mobile app developer is versed in the development task, but he must maintain constant communication with his clients.

By doing so, he will be successful to avoid the prospective mistakes and can render the best results within the stipulated time frame. So, follow these steps and see the results.

Boost the Speed of Mobile Phone

  • Software Updates
    One of the reasons why smartphone makers provide updates for their phone every now and then is to ensure that their performance is optimized to the best that they could and fix bugs if there are any. Every release is expected to work best towards the phone’s performance boost, of course. Aside from that, these updates are meant to fix all other issues that users experience with the phone according to their feedbacks. These issues are mostly about app performance (or non-performance – crashing) and the phone’s speed. So, if ever your phone notifies you of a firmware or system update, make sure that you don’t miss out on that no matter how big of a size it is. In fact, the bigger the update the better.
  • Clear Cache Data
    Cache data can be considered as the leftover files from your previous browsing session, app usage, or residue of apps you’ve once installed. These files usually hide inside the system folders of the phone and are not easily detectable through the phone’s native file scanning capability. In order to get to these sneaky junk files lingering within your phone is to install a performance optimizer or file cleaning app, the most common in the Android market is the Clean Master and Dr. Cleaner for iOS. Apps like these two will make a thorough system scan of your phone and will determine files and folders which are no longer in use and have been that way for a period of time already. Once done, it will give the users a run-down of these files and option to remove them entirely. On the average, releasing a month’s worth of cached files will give your phone more or less 1GB worth of storage memory. Not only will it give you more room for your files, it will also make your phone’ software lighter does boost its performance.
  • Deleting Unnecessary Apps
    As mentioned earlier, the more storage space in your phone is consumed, the clunkier it will get. One of the ways to optimize storage space which will lead to a performance boost is to delete unnecessary apps especially bloat wares. Bloat wares are preinstalled apps that phone makers decided to throw into their phones in order to achieve the actual features that they want to emphasize on their phone. Some of these bloat wares are useful but most often than not they’re useless. Also, many of these bloat wares cannot be uninstalled but there’s still a good sum of them that can be removed from your phone.

Useful Tablet Accessories

Ports

Most of the latest high-end tablets include a Micro USB port to give greater device flexibility in relation to learning and entertainment. By investing in an adapter it is possible to connect the tablet to a wide range of USB accessories. A practical use for this port is the ability to connect the tablet to a large screen for ease in checking out presentation files for work, watching a movie on the large screen, or to share photos with others.

Keyboards

A tablet hooked up to a wireless Bluetooth keyboard makes it possible to complete a wide range of tasks that are usually left for the desktop computer or laptop. An external keyboard increases the function of the tablet and improves productivity to get things done easily and quicker. They are particularly useful if planning to write a long report or email away from the office. Plus, the keyboards designed for a specific tablet will often include several one-touch shortcut keys to further enhance the use of the device.

Battery charger

The modern tablet doesn’t have the longest battery life and requires a regular recharge to keep going. Batteries are depleted even faster when watching movies or playing fast-paced games. A simple solution to keep the tablet powered up is to invest in an external battery. They have the potential to significantly extend the usage life of the tablet and keep it running for the nearly the entire day.

Internet Security Product Guide

The ideal internet security suite for you will depend on your own needs. Do you really need premium protection or will basic protection be enough? The latter should be fine as long as you only need protection for a couple of PCs in your home network, or an antivirus app for your mobile device. However, these days, many people need more than basic protection.

One of the reasons why people want to purchase product licenses for premium security products is because they those licenses tend to cover multiple installations on a wide number of devices and platforms. You can purchase licenses for your Windows PC, Mac, Apple OS device, and so forth.

Another very useful feature is the anti-theft tools that allow the user to track down the lost or stolen laptop or smartphone. Since a single device can contain so much private and personal information regarding your identity, it’s crucial that you are able to keep track of it at all times. Backup software / online storage features are nice as well since they allow you to back up important data on the cloud.

There are usually a couple of different products for home users and businesses. You likely won’t need as much security as a business, but you’ll still want something better than a basic antivirus program.

Speed is another important factor – many internet security programs are known to take up too much bandwidth. Read reviews on a product before purchasing to see what other users are saying about its speed. Does it slow the system down too much, or does the PC or mobile device still run efficiently? If the security suite includes a VPN, does that VPN offer a wide variety of virtual server locations? Will the connections be fast and stable?

Whichever internet security product you choose, make sure there are coupon codes that will help bring the price down, regardless of whether you order a one-year subscription for the protection of three devices or a three-year subscription for five devices. One product that is really worth looking into is Kaspersky Internet Security. It offers reliability, different payment options, good customer service, fast speeds, and more.

Hybrid Databases

  • Do you see your data set growing to larger numbers?
    If you have a product offering that serves a niche you feel has amazing potential, setting up a hybrid database from inception can reduce the number of headaches that would arise from a newfound spike in traffic or complexity of the transactions being performed. If you feel that your database will grow at a slower, more organic rate, you may never need to employ hybrid database architecture. Strong consideration should be given to the hybrid options, if you feel that there will be upward momentum at a fast pace.
  • Will the database interactions be highly transactional or minimalistic?
    This is an important question to consider because a singular transaction will take up a much smaller amount of space than a query that has several components. It’s far easier to maintain a database with one million users that only complete a single query, than it would be for those same million users to execute transactions that have multiple components. The space required for complex transactions is far greater than that for a one-and-done use.
  • Is your current database slow or clunky?
    Usually, if this persists for more than a few weeks, procrastination has set in and your employees are numb to the fact that they’re just going to have to wait for the pinwheel of doom to finish processing their tasks. When the database begins to get slower, it’s only a matter of time before it has to be upgraded or replaced altogether. By switching things up to a hybrid database, your employees will be able to experience the best of both worlds, as far as databases are concerned. The SQL side of the equation allows for transactional queries and the NoSQL side allows for CRUD Operations (Create, Read, Update, Delete).

Several aspects of the hybrid database make it popular with the SaaS crowd. One reason is that they increase the application performance, especially when it comes to the read/write operations. Another advantage lies in the fact that the database allows for data distribution across lower cost clusters, all while maintaining ACID properties across more sensitive portions of the dataset. Increased reporting ability across large datasets is also another feature that increases productivity and keeps the project on track.

Deal With Google Panda

Google has hundreds of quality-controlling mechanisms. Among them, its Panda seems to be one of the most merciless systems that neutralizes the copy-contents. As a result, affiliate sites appear to get affected badly. The Panda impact can affect 20 to 80 percent of websites overall. It can cause miserable dips of search visibility for a large chunk of websites across the Google search engine.

However, this impact is limited to those websites which have infringed the copyright terms and conditions by copying contents from others and overlapping the same or similar topics with marginally different keyword variations. Allegedly, the Panda swipe cannot sometimes distinguish the original websites from the duplicate ones and that results in poor traffic performance of the original websites. Despite this allegation, Google claims that Panda considers original contents and gives ranks duly to them. Also, it values for the unique design, original content and good navigational speed of the web pages, among others. If Panda finds that web contents are meeting its parameters perfectly, it will give proper ratings to them. As a result, the flow of the web traffic to those web pages will swell automatically.

Nevertheless, thousands of website-owners are voicing against this artificial intelligence in the fear of losing page ranks and huge web traffic overnight. But, Google insists on its preference for quality contents over quantity. This giant search engine has made its stand clear in its official blog post that contains 23 relevant questions. If the website-owners go through that set of questions, they will come to know what kind of contents can qualify the Panda parameters.

Now, the myth about the Search Engine Optimization (SEO) that is believed to be omnipotent will perhaps lose its significance. Panda says that redundant articles with spelling, stylistic and factual errors will no longer get a free-pass. Only quality, topic-based, research-based, informative, authoritative and flawless contents will help optimize the traffic flow of web pages and that will eventually improve their page rankings across the Google.

Reputable SEO Companies

  • The major objective of a website used for business ventures must always be to build up conversion and not merely website traffic. The ultimate aim is acquire more traffic that could be transformed into income. The volume does not guarantee the success of the enterprise. A good number of daily visitors should be convinced to buy from you. This decides the profitability of your initiatives.
  • Website owners should be capable of classifying the types of visitors with the help of the best SEO companies. There are aggressive visitors who know the requirements and what they want from websites. There are methodical clients who will require many details and find time to assess these before opting to buy from you. Accuracy and logical judgment are relatively important to them. The irresponsible visitors are not so sure about their needs but anything that catches their attention can urge them to buy immediately. This category is easily impressed by website videos, pictures and graphics as well as promotional offers and bonuses. Finally, the social client is often knowledgeable about social networking and are inclined to check with a lot of friends and associated before deciding to purchase any merchandise. These people are brand and product-conscious.
  • Website owners should consult expert about the attitudes and characteristics of visitors. This will enable them to highlight the principal features and benefits of their goods and services. These business managers must be able to make use of techniques that can induce the shrewd or cautious customer to buy from them.
  • Social networking is crucial to websites. This unique concept is a big help to the marketing efforts of online entrepreneurs. A social bookmark is valuable although the bookmark appears on a freely accessible social media site. Other people can perceive the bookmark and be exposed to the content of the website. As a bookmark obtains more views, its importance in the social site is enhanced and will drive more and more users to your site. The aim here is to have one of the bookmarked pages emerge on the homepage of a social site.

Look Into Cybercrime

In the early years of conception, cybercrime was not as wide spread as it is today. It was usually committed by a rogue individual or a small group of individuals just looking to snoop around some company or personal information. A majority of the intrusions where an attempt to see just how deep they could penetrate without being discovered. The intentions of those individuals were not always criminal, however, their actions where considered to be, even though there was usually no permanent damage other than acts of snooping.

In a short amount of time, cybercrime rapidly evolved from snoopers into those seeking to extract information or deploy viruses. When you consider the evolution of cybercrime, it’s similar to the evolution of the security of a bank. Early on, banks were far less complex then the banks of today so accessing them for information or financial gain was an easy process, i.e., banks from the early 1900’s would have been far easier to access then the complex banks of today.

Today cybercrime is one of the fastest growing areas of crime. The issues surrounding cybercrime are far more complex and organized. It is evolving and spreading at an alarming rate. Organized crime syndicates work together to cover a wide range of cybercrime activities for the sole purpose of financial gain. Their intentions are criminal, and this pool of individuals continues to grow rapidly.

Because cybercrime is a faceless method of performing criminal acts, an increased number of criminals exploit the accessibility and anonymity that technology offers, and unlike most normal criminal activity, the challenges we face with cybercrime wont be met just at the local level. The global nature of the internet has provided the flexibility for criminals to perform nearly any illegal cybercrime, to anyone they choose, from any location around the world. This is a bad combination for a society that is becoming more interconnected through technology by the day.

Some modern methods of cybercrime include hacking, cracking, identity theft, internet fraud, cyber intrusions, bank fraud, corporate security breaches, spearfishing, and email fraud. Setting up defenses against cyber criminals will become increasingly harder for companies to keep up with demand. In fact many experts today believe we are not winning the battle against cybercrime, and that the amount of criminal hackers exceeds the amount of ethical hackers. A trend that does not seem to be changing anytime in the foreseeable future.

Linux Server Hardening

This is directly at odds for the increased necessity for comprehensive security measures in a world full of malware, hacking threats and would-be data thieves.

Most organizations will adopt a layered security strategy, providing as many protective measures for their IT infrastructure as are available – firewalls, sandboxes, IPS and IDS, anti-virus – but the most secure computing environments are those with a ‘ground up’ security posture.

If data doesn’t need to be stored on the public-facing Linux web server, then take it off completely – if the data isn’t there, it can’t be compromised.

If a user doesn’t need access to certain systems or parts of the network, for example, where your secure Ubuntu server farm is based, then revoke their privileges to do so – they need access systems to steal data so stop them getting anywhere near it in the first place.

Similarly, if your CentOS server doesn’t need FTP or Web services then disable or remove them. You reduce the potential vectors for security breaches every time you reduce means of access.

To put it simply, you need to harden your Linux servers.

Linux Hardening Policy background

The beauty of Linux is that it is so accessible and freely available that it is easy to get up and running with very little training or knowledge. The web-based support community places all the tips and tutorials you’ll ever need to carry out any Linux set-up task or troubleshoot issues you may experience.

Finding and interpreting the right hardening checklist for your Linux hosts may still be a challenge so this guide gives you a concise checklist to work from, encompassing the highest priority hardening measures for a typical Linux server.

Account Policies

  • Enforce password history – 365 days
  • Maximum Password Age – 42 days
  • Minimum password length – 8 characters
  • Password Complexity – Enable
  • Account Lockout Duration – 30 minutes
  • Account Lockout Threshold – 5 attempts
  • Reset Account Lockout Counter – 30 minutes

Edit the /etc/pam.d/common-password to define password policy parameters for your host.

Access Security

  • Ensure SSH version 2 is in use
  • Disable remote root logons
  • Enable AllowGroups to permitted Group names only
  • Allow access to valid devices only
  • Restrict the number of concurrent root sessions to 1 or 2 only

Edit sshd.config to define SSHD policy parameters for your host and /etc/hosts.allow and /etc/hosts.deny to control access. Use /etc/securetty to restrict root access to tty1 or tty1 and tty2 only.

Secure Boot Only

Remove options to boot from CD or USB devices and password protect the computer to prevent the BIOS options from being edited.

Password protect the /boot/grub/menu.lst file, then remove the rescue-mode boot entry.

Disable All Unnecessary Processes, Services and Daemons

Each system is unique so it is important to review which processes and services are unnecessary for your server to run your applications.

Assess your server by running the ps -ax command and see what is running currently.

Similarly, assess the startup status of all processes by running a chkconfig -list command.

Disable any unnecessary services using the sysv-rc-conf service-name off

Restrict Permissions on Sensitive Files and Folders to root Only

Ensure the following sensitive programs are root executable only

  • /etc/fstab
  • /etc/passwd
  • /bin/ping
  • /usr/bin/who
  • /usr/bin/w
  • /usr/bin/locate
  • /usr/bin/whereis
  • /sbin/ifconfig
  • /bin/nano
  • /usr/bin/vi
  • /usr/bin/which
  • /usr/bin/gcc
  • /usr/bin/make
  • /usr/bin/apt-get
  • /usr/bin/aptitude

Ensure the following folders are root access only

  • /etc
  • /usr/etc
  • /bin
  • /usr/bin
  • /sbin
  • /usr/sbin
  • /tmp
  • /var/tmp

Disable SUID and SGID Binaries

Identify SUID and SGID files on the system: find / \( -perm -4000 -o -perm -2000 \) -print.

Render these files safe by removing the SUID or SGID bits using chmod -s filename

You should also restrict access to all compilers on the system by adding them to a new ‘compilers’ group.

  • chgrp compilers *cc*
  • chgrp compilers *++*
  • chgrp compilers ld
  • chgrp compilers as

Once added to the group, restrict permissions using a chmod 750 compiler

Implement Regular/Real-Time FIM on Sensitive Folders and Files

File integrity should be monitored for all files and folders to ensure permissions and files do not change without approval.

Configure Auditing on the Linux Server

Ensure key security events are being audited and are forwarded to your syslog or SIEM server. Edit the syslog.conf file accordingly.

General Hardening of Kernel Variables

Edit the /etc/sysctl.conf file to set all kernel variables to secure settings in order to prevent spoofing, syn flood and DOS attacks.
