Essential Functions of Remote Database Administrators

A corporate database involves numerous different kinds of data, but necessarily data that is required for the most critical applications to run. It includes data of great importance to the company as well as to the employees and customers. Without the data or the primary functioning application there is likely to be no or little productivity. Hence, it is essential that administration and the control of the crucial data be handled by a professional remote database administrators or DBA for short.
Here, I have mentioned some of the primary functions of remote database administrators:
1. By considering the design of the data structure and architects, the remote database admin should participate in the implementation of the database and the database management system into the ecosystem. In most cases, the system may already be up and running and the database admin might just have to run some maintenance tasks.
2. Monitoring and analyzing system performance of the databases. The analysis must seek for an overall performance, i.e. of data and disk optimization such as disk usage to predict for future expansion and in majority writes versus majority reads.
3. Regular maintenance and repair for the system. Proper maintenance would require periodic indexing through use of the database management system. Employing daily and automated system. Using a daily automated system check would also facilitate the admin by alerting the database admin if there are any possible threats or problems to be addressed. It task also encompasses simple works like adding and removing users access or changing access rights for the existing users. Maintenance also entails scheduled backups and troubleshooting minor issues.
4. Maintaining and implementing security and vendor patches for the database. This is one of the most critical services performed by the administrators. Security should be restrictive. Tasks like data writes should only occur programmatically through the mission critical applications or other approved software. There could be other methods but this is the only way to maintain data integrity.
5. Developing and implementing business continuity and disaster recovery plan. This in turn goes back to security and maintenance and beyond both issues to the extreme. Business continuity demands full 100 % uptime. Using multiple nodes with an Oracle database facilitates multiple servers to be integrated into a RAC (Real Application Cluster) which would prevent downtime if installed properly. This configuration will facilitate in achieving flawless recovery when one of more of the professors or servers are affected. Disaster recovery and business continuity will be a part of a larger corporate initiative and encompassing all critical systems and not just the domain of the administrator.
6. Since the database administrators perform highly specialized functions, it would be cost effective to acquire a Database administration service to perform such functions across multiple locations or a single location. The remote DBA are capable of performing all functions through network connections to the targeted location or multiple locations. This is an essential technology resource in every corporate environment with a critical application.
Remote System Administration and Remote System Management have become crucial aspects of every application development industry. It has facilitated development industries with cost effective solutions and more manageable approach to database management.

Cloud Computing Security Issues

Cloud computing brings many innovations and advances in the information technology fields. Cloud allows businesses to focus on their business. It does not solve all of today's security problems and can cause more security problems that will need to be addressed. The power of cloud computing can be harnessed against other clouds to limit there performance. New attacks on the cloud system will keep security engineers busy to keep your data secure. Cloud computing is a colloquial expression used to describe a variety of different computing concepts that involve a large number of computers that are connected through a real-time communication applications and networks.

High availability and central administration make cloud with fast moving requirements make it appealing to cyber crime related people. What happens when an attacker gains access to your personal information. They can use credit card information to open different accounts. Critical applications housing sensitive data should not be built on a community or shared AMI. The difficulties of detecting malicious code are enormous and hackers know this. Each cloud service provides an interface to manage the system in the cloud which can introduce security risks. If an attacker is able to gain access to the management console directly he can alter the way the application runs.

With cloud based offerings attacks are not as clear cut when dealing with stand alone systems. The attacker is able to tamper with the virtual machine settings or can modify the application running they will have access to your data on that virtual machine. Once a hacker gains access to a user's session he will have a wealth of personal information. Once the vicious AMI is launched from the account holder it can perform a number of malicious actions and take much personal data. After an attack the victim can see data was removed without their consent.

The hacker can attack the different billing models of the business and collect information on credit cards and personal data.The attacked application can charge the victim for going over their capacity since it can require band with to stop the attack. Today we use computing in very large amounts which make us targets to hackers.

Cyber Security and the Emerging Security Threats

Cyber security has been associated with the ever-growing complexities, threats and even costs which are popping up and growing unprecedentedly each passing day. Devices are getting interconnected and this has brought about the many perils in the cyber world. The interconnectivity has made it easier for hackers and criminals to compromise data both on the large scale and irrespective of where it is found. Security risk management has continued to be headache to many different groups of cyber users who happen to be the businesses as well as individuals. The need to proactively protect web applications, web processes and above all data has to be approached with a lot of seriousness and compliance to eliminate all types of threats both external and internal. Not only are cyber attacks the most feared threat but the sabotage of infrastructure is feared since incidences are growing in number each passing day.

The ever-changing cyber security landscape has people, organizations and businesses on their toes in identifying risks and vulnerabilities in their resources and systems. Threats as earlier mentioned have been on the rise due to the communication networks expanding and being in a position to gather humongous amounts of data. Yet another form of threat has been the rise of digital and cyber weapons which have been designed and deployed to target specific control systems or targeted at data stored in them with the intention of bringing each of these down. It should be remembered that the threats to infrastructure arises from the increase in access points within the network. Other threats have been the theft of data especially from governments, the theft of intellectual data property, the theft of financial information and cyber attacks aimed at the mobile devices.

The cyber security landscape this year has seen the problems and challenges which have been presented by mobile devices and applications. The use of the mobile devices has continued to grow and this growth has been matched in the growth of cyber attacks aimed at these devices. The growth of the mobile app niche has also seen an increase in the threats hidden and associated with many apps now found either free or at a small fee. The apps which are location based will have the risk of threat is when the applications are packaged with malicious code and malware such that they are then sold or availed to unsuspecting users. Other applications have been made in such a way that they will download malware and such programs like keyloggers and others that will record phone calls and the text messages.

The social engineering threat has been also on the rise with the intention being people will click on malicious links through the use of rogue antivirus and other many rogue and fake software like fake backup software mimicking the cloud computing services.

Hactivism has also been on the rise with different people or groups of people registering their displeasure and their non compliance with political decisions and opinions and other social factors through the staging of cyber protests. Their biggest tool has the denial of service attacks that are intended to bring down websites and systems. The DoS attacks will limit or totally disrupt the access of data on various websites and across a network. The other form of attacks has seen the posting of sensitive information such as the email information and credit card information which have been stolen or hacked.

The advanced persistent threat is another form of attack which takes the shape of a longterm hacking which is often targeted through subversive and stealthy means at intellectual property. Espionage is one form and the other is capturing network by working on vulnerable points. A network once captured will be used to store data and information and for other people a relay point. The spear phishing attacks are aimed at businesses and the top echelons of organizations with the aim of obtaining some confidential data or gaining access to networks and the businesses.

With so many threats faced in the cyber world, sound security practices need to be used both by individuals and businesses. The practices and measures taken are those that guard against attacks and cyber challenges and ally the impact of an attack.

What Would a Hacker Gain From Hacking?

Crackers and Hackers

The first interesting thing to know is that there is a difference between a hacker and a cracker. A hacker tries to test a system for possible security and network breaches, tries to learn as much as possible from a system and tries all strategies to check the system for its optimum performance level. That is all positive and no malicious intent. Whereas a cracker tries to bypass system's security checks for achieving his evil gains such as:

Stealing data about the registered usersGetting hold of credit card numbers and passwords for obvious reasonsFinancial or business informationSome other information for providing potential damage to the owner of the systemThey can get passwords with usernames and personal pictures and photographs of family and dear onesOur computer can also be used for Denial of service attacks on other PC'sCrackers can then sell on this stolen information to online spammers. This can eventually lead to an alarming increase in the traffic to some organizations' website for possible crash down of its server. The PC can also be used as spam bot

There is so much that a cracker can do that there is not limit. One thing for sure is: every system that goes online needs to be protected against such attacks. The bigger the website or organization, the more risk it is at.

Why do Passwords Leak

If you are into playing computer games and visiting online gaming websites, you should be aware of the potential cracking threats that your system is prone to. Gamers have the tendency to create accounts on many websites' forums and bulletin boards to get informed of the latest updates and cheats etc. When they create their accounts on many websites, they leave their usernames and passwords with them. The more information you have on internet, the more at threat you are. Moreover, humans are designed to be inclined towards simple and easy paths so we choose passwords that are easy to remember and this makes them much easier for the crackers to crack.

Various methods can be used to crack passwords like the brute force attack where a system is bombarded with commonly used words from a dictionary and this is where easy to remember passwords can be really helpful for the crackers. Downloading game mod is also a potential security threat. Such software can also contain viruses that are downloaded with them and settle in the PC, hidden from your reach and knowledge. Such viruses can also save keystrokes and hence your passwords and usernames or any such information can be leaked.

This article gives a brief overview of online gamer safety and the potential threats that a gamer's system is prone to. If you want a more detailed information on all possible types of attacks and how to protect your privacy, read The Gamer Safety Guide.
