With many malware and ransomware attacks happening on numerous systems, many companies and households are wondering just how safe their network connections are. With network security that seems like it is working, it may not be protecting your systems against all of the threats that happen to the computer.
With many viruses rapidly spreading and changing the way they infect these systems, a lot of the antivirus software is unable to provide the full protection against the newest viruses. Protecting yourself from ransomware is a must when it comes to protecting your system and all that comes with it.
Take a look at some more information regarding ransomware and the ways that you’re able to protect yourself and your computer against it.
What exactly is Ransomware?
Many viruses are growing and spreading, but not a lot of people know what these viruses are. One of the most popular of these viruses is ransomware. So what are these viruses?
Ransomware is a type of virus that requests payment in order to have access to the files that they have encrypted and locked so the user cannot gain entry to them. Usually the price is high for just one folder. Additionally, they may disguise themselves as virus cleanup programs. When these are downloaded, they control the computer and may say there is a virus so the user has to pay to have the virus removed.
Since the discovery of these practices and viruses, many people have gained new insight on them. However, this only made them grow. They now have three distinct types of viruses that can be used to create problems within many systems.
Why Does it Keep Growing?
Many people think that when you remove a virus, a new one is not going to take its place. Untrue. When a virus is removed and figured out, a new one that is harder to crack comes out in its place. There are always codes out there that have to be solved, it will continue to be a never-ending problem.
The rise in the number of systems that do not have protected firewalls on them has allowed these viruses to leak into the system. Those that do not know about these attacks might find themselves paying to have access to their files again. The virus works, so they will continue to do it.
How does it catch users?
There are numerous ways that these hackers are able to get into systems and infect them. With attachments being sent in emails or even links that ask the user to click them, each of these has its own set of warnings. If the person has no virus protection, they may end up with the virus because there is no warning stating that the link or the attachment may be infected.
Due to this, many phishing emails are sent out. Email inboxes generally catch these emails that are offering viruses to the unsuspecting recipients, but in the case that the email goes through, many people fall victim to the viruses.
Protecting yourself and your system
These viruses are expected to grow and expand to other systems in the coming years. Due to this, many people have to stay vigilant against the viruses that are looking to control their systems. These hackers do not care if you have nothing to give, if they take your precious family moments or anything else. They’re looking to scam people out of as much as they possibly can. They target whoever is willing to pay, it doesn’t matter anything about them. Due to this, it is important to protect yourself at all costs. You do not want to fall victim to their crimes.
Use these tips for protecting yourself against ransomware attacks so that you’re able to feel secure when using your system.
There are also many other ways that a user is able to protect themselves against these threats, but using these top solutions can ensure that your network security is up to date.
It is best to be safe, not sorry when it comes to protecting your system against ransomware. You want to ensure that you’re protecting yourself entirely. When something like this happens to a system, it is important that the person speak with someone that is able to remove the virus and then restore the system to how it once was. If there was no backup, all of the data can be lost in this restoration. It is important to protect yourself against these viruses, as they can cause serious damage and the hackers can have access to all of your information stored on your system.

Over the last five years, big data has become one of the most valuable assets in business. Although the process of gathering and storing large quantities of digital information has been around since the nineties, it’s only in recent years that it’s been put to good use. Indeed, as Harvard Business Review’s Kristian Hammond noted in 2013, big data is the means to evidence-based decision-making. By analyzing large quantities of information from a variety of sources, companies can make better decisions and, in turn, grow in a more efficient way. Taking this concept, companies of all sizes and persuasions have developed technology to harness the power of big data.
As per a 2016 report by Forrester and TechRadar, the industry is evolving rapidly. The report noted the trend trajectory of 22 technologies within the big data sector, many of which have flourished as predicted. Of those highlighted, Forbes Gil Press noted 10 of the most significant for businesses:
Predictive analytics
This is the process of using data mining, statistics and modelling to make predictions about future outcomes. In other words, historical data defines a set of parameters, which computers can then use to determine what user behaviour/responses might be in the future.
Search and knowledge discovery
These tools support self-service extraction of information from large, unstructured databases. In other words, search and knowledge tools allow someone to input a query and pull in data from a variety of unconnected sources in order to cover a single topic/request.
Stream analytics
This technology can take information generated from a variety of connected devices and sensors and turn it into actionable insights in real-time. This technology is most concerned with IoT and using data from a variety of smart devices to make almost instant predictions. For example, stream analytics could be used in an IoT home system to help determine the optimal living environment (heat, lighting etc.) for the user based on masses of data from the thousands of homes.
NoSQL databases
The use of NoSQL databases makes the processing of some big data sets more efficient. Because these databases are structured using key-values, graphs or documents instead of tabular structures found in relational databases.
Distributed file stores
These systems store data on multiple nodes instead of a single point. The data is replicated on each node to allow for improved processing performance i.e. the information is more readily available. This type of data storage is similar to the decentralized structure of blockchains.
In-memory data fabrics
This technology groups independent sources of data into a grid. This grouping not only allows each source to operate independently but as part of a collective, through which information can be analyzed either in parts or as a whole unite.
Data virtualization
Drawing information from disparate sources, this technique allows users to gain an overview of large sets of data in real time. This is possible because the software doesn’t replicate the data from each source. Instead, it simply delivers a unified data service that can support multiple applications and users.
Data preparation
With big data insights increasing, it’s becoming increasingly difficult to process it all in an efficient way even with all the current software on the market. Data preparation involves collecting and editing data from multiple sources before it’s plugged into a system and analyzed.
Data integration
To improve the communication between unconnected data sources, integration software has become important. Through products such as Apache Pig and MongoDB, it’s now possible to link data in a meaningful way even if the sources are completely unconnected.
Data quality
Not all data is good data. With speed and efficiency crucial in today’s world, businesses are now using products that analyze and cleanse data before it’s stored/analyzed.
Predictive Analytics starts to shine
Of the innovations listed, predictive analytics is one that’s showing it has the most utility in the current business climate. Despite the fact it’s been around for more than a decade, machine learning (a part of the artificial intelligence realm) has made this technology more effective. Prior to machine learning giving computers the ability to adapt in real-time, predictive analytics struggled with scale. Because AI systems can operate without human intervention, they can process more information. As an example, Magnetic’s AI system can process 1 petabyte of consumer information to suggest potentially profitable actions. Combining this technology with predictive algorithms can result in models that consider more information and, in turn, generate more precise outputs.
In simple terms, predictive models allow businesses to determine customer responses or potential purchases by using historical data. An example of this would be the way gaming operators draw data from in-house marketing campaigns and external comparison sites to define their next marketing campaign. For instance, after sending out a promotional email, the company has the ability to record the number of clickthrough responses. On top of this, affiliate data from comparison sites gives the company further insight into what’s hot and what’s not. Indeed, because a platform like Casinos Killer ranks sites using a myriad of data, including betting options, bonuses and overall quality, it’s easy to see which offers players are attracted to. Just like PriceGrabber and NexTag are hotbeds for user preferences, the same is true in the gaming sector. So, by tracking data from affiliates and combining it with its own insights, it becomes possible to use predictive analytics and AI to highlight trends and launch campaigns based on this analysis.
Of all the trends in big data, the evolution of AI-powered technology is by far the most significant. As we’ve shown, the ability to process larger quantities of data in real-time can result in more accurate predictions. The upshot of this is that business can be more efficient in whatever task it is they’re interested in. Whether it’s security or marketing, the crossovers between big data technology and AI are playing a central role in the action.

We recently interviewed Nicole Nguyen, Head of APAC, Infinity Blockchain Ventures, who spearheads Infinity Blockchain Lab’s regional initiative in connecting major players and fostering an ever-growing blockchain ecosystem in Asia. She is a co-author of the first Vietnam Blockchain Landscape Report and speaker at various international and local blockchain conferences such as TEDx, Shanghai Blockchain Week, World Bank blockchain workshop series, Seamless Asia and ConnecTech Asia.
Nicole Nguyen will be speaking on the panel ‘Fireside Chat: 10 Key Challenges to Blockchain Adoption’ at ConnecTechAsia Summit on Day 2, 27 June 2018. She shared her views on the new trends, challenges and myth about blockchain technology today.
Read the complete interview below:
1. Can you give us a brief introduction about what this technology is and what is the principle on which blockchain technology is based on?
Blockchain, at the end of the day, is a database. Yet what brings magic to blockchain is the underlying cryptography, consensus algorithms, decentralized database and network. Technically blockchain is not something new – its inception dates back to the 90s yet as a trust-centered technology, blockchain is drastically transforming the way we exchange data and value. By changing the fundamentals of a society – trust and value, blockchain is deemed as a game-changer to the global innovation landscape.
2. Are there different types of Blockchains? What are they?
By definition there are various types of blockchain. To my understanding, basically there are permissioned, permissionless and hybrid blockchains. In permissioned blockchain, the system owner can designate transaction validators and have the authority to remove or alter the data; also the data is only accessible to pre-selected audience. However this is not possible in a permissionless blockchain – arguably claimed as the most democratic blockchain. Hybrid blockchain allows a mixed model where pre-selected nodes or players can validate/approve the data and the public is allowed to see the data yet have no authority to rewrite the data.
Subject to different business requirements in terms of system robustness, privacy, throughput etc, you can consider the most relevant blockchain and most importantly how blockchain could fill the unmet demand in the market like no other technologies can.
3. How will blockchain reshape the future, maybe in next five years? Who are going to be the biggest beneficiaries of blockchain technology and why?
The blockchain is transforming the way people exchange information and value like never before. This is seriously disrupting value and growth drivers of the society and ushering new business models and opportunities. At the end of the day, end users will be the biggest beneficiaries of blockchain in my opinion, yet startups and disruption incumbents such as mainstream players and businesses can find their own way of leveraging blockchain technology to bring about higher efficiency, productivity and sustainable growth to the business.
4. What are the key challenges that the technology needs to overcome today before mainstream adoption?
The blockchain is still at its infancy in terms of awareness and development and challenges still amass such as scalability, lack of regulation, on-boarding process etc. I personally feel there is a shortage of good blockchain products at infrastructure level (payment, exchange, identity etc.) with easy on boarding process and user-friendly interface. Simply as it might sound, I think this is one of the key challenges to blockchain adoption.
5. There is a lot of myths about blockchain right now. Can you name a few and debunk them?
Myths include the following – Blockchain is cryptocurrency. Blockchain brings money from the sky. The blockchain is the trend – you should apply it at all costs. There are plenty of them.
I think my key takeaway is behind the hype and flashy covers, blockchain is all about being relevant when it comes to application in businesses. Once you want to apply blockchain please make sure you have a sharp problem statement and blockchain is the only technology that can fill the missing piece.

SQL Server and SQL databases are here for quite a while, and there are many techniques and strategies available for the administrators to perform better in it. Many DBAs will not be aware of some of the top tips which will help you mainly in a production environment. Here, we will discuss some random tips which some of you may find informative and helpful in the job of an SQL Server production DBA.
#1. Forfiles utility to get rid of old backup files
Forfiles (forfiles.exe) utility comes pre-installed with Windows Server 2003. IT enables the administrators to perform batch file processing. So, DBAs can use this service in conjunction with the SQL Server Agent, which help delete the old database backups, which will eradicate dependencies on SQL Server maintenance, xp_cmdshell extended stored procedures or the VBScript objects.
#2. Using ‘ALTER USER’ to repair orphaned logins
From SQL Server 2005 SP2, the ALTER USER command of T-SQL’s is having a WITH LOGIN clause too. Choosing this can repair the orphaned logins by changing the user’s SID to security identifier of server login. It can improve not only SQL Server but Windows logins too. Orphaned users get created when a database gets restored from a different server, and that login is independently produced.
#3. Use the ‘sp_addsrvrolemember’ to take up sysadmin role
From SQL Server 2008, sysadmin role is not given to Windows Administrators by default. To cover this, you can initiate SQL Server instance in the single-user mode or maintenance mode and then run ‘sp_addsrvrolemember’ in the Sqlcmd utility stored procedure to add your login to the sysadmin role.
#4. Using PortQryUI for troubleshooting connectivity issues
As suggested by RemoteDBA.com experts, you can use the Microsoft’s PortQryUI to troubleshoot the TCP/IP connectivity issues. PortQryUI is an alternative to PortQry but has a GUI with many predefined services. One of these predefined ports group is meant for SQL Server, consisting of a TCP port 1433 and UDP port 1434. To check the ports, you can just enter IP address or the FQDN (Fully Qualified Domain Name) or target SQL. It is easy to download PortQryUI utility at “PortQryUI.”
#5. Try and use a unique strategy while running the DBCC CHECKDB against bigger databases.
Databases tend to become larger day by, so the maintenance procedures like checking integrity with the DBCC CHECKDB command of T-SQL’s may take longer and longer. There are several potential solutions if the DBCC CHECKDB exceeds allocated maintenance period. One instant solution is to access backup to restore DB on a different server and then run the DBCC CHECKDB against the existing server. A second solution is to custom set database’s verify option to CHECKSUM and then run DBCC CHECKDB with PHYSICAL_ONLY option. This combination will make the DBCC CHECKDB run in lesser time, but will still catch the I/O subsystem.
You can also use the T-SQL’s Server 2008 Center Management servers and local server groups to query multiple servers simultaneously. In an SQL Server 2008, you can also use local server group to connect to the servers frequently accessed quickly.
