Targeted attacks on the network of a business can be big trouble. A business should know where to look and what to look for to stop the attacks.
Businesses are aware of the dangers of hackers. They know that a hacker can steal private information that hey store on their computer networks. They recognize that hackers can create problems for the business and the business's computer systems through a variety of different ways.
Being aware of the dangers and knowing what to do about them is not the same thing. Unless a business has a big IT department, their ideas about network security are not always correct. They may not realize that they are the target of hackers. They may assume that hackers either try to cast a wide net with the hope of catching someone or they target bigger companies. A smart business recognizes the threats of targeted attacks and knows where and how to look for them and what to do when they find them.
What Are the Threats?
Businesses have changed. They store more and more Information on computer systems and on the cloud. The information is the target of the hackers today. The hackers are not the same they were in the past. They have come up with tools to get past the security systems that businesses have in place. Businesses keep working to improve their security and the hackers keep working to get around it. That is why businesses need to know where the hackers are trying to attack.
7 Points of Attack
1. Domain Name Systems - These are known as the DNS Records. Hackers try to fool people searching for a business on the internet by creating domain names that are similar to the real business domain address. If people make a mistake typing the name of the business they could end up landing on the wrong website and may share information with the hacker instead of the business.
IT security intelligence can check for potential problems from these DNS records. They can search for a variety of things that are signs of hacker's attacks, including unknown domains with specific IPs, Domains that were recently registered that are unknown, domains with random characters or domains that imitate other legitimate domains.
2. Heed the Warnings of Security Systems - Computer systems will send out alerts of possible problems with the security systems and files. A business often assumes that the warnings are false alarms if they recognize the file or information that the threat intelligence services are giving them. It is not always a smart idea to ignore these warnings.
Network security intelligence will help prevent the attacks on a network. It can spot the hackers when they are trying to get into the computer system of a business. The only flaw they have is they require the user of the intelligence services to act on the threats they find.
3. Unknown and Large Files - Hackers plan their attacks in advance. They work to place large unknown files on the computer systems of a business. Regular searches for these types of files with cyber security intelligence software can prevent hackers from ever using them.
4. Watch the Network Log - Audits of the network log for strange or abnormal connections is another way to stop attacks from hackers. This requires someone to understand what the normal activity of the business network looks like. The only way to see activity that is out of the ordinary is by being aware of what is supposed to happen on the network.
5. Check the Logins - Hackers do not always have a password to login to computer systems and business accounts. The login record can show the business failed attempts at a login to the network or the computer systems of the business. Unusual amounts of this type of activity is a sign of a hacker. To maintain the security of a network, the business should do regular audits of these records.
6. Unusual Protocols - Like the unusual connections, spotting abnormal protocols is not easy. Hackers are smart and will try to use protocols based on the way the businesses network operates. Spotting something that is out of the ordinary requires looking past the first layer of the protocol connection and studying the content of the connection.
7. Look at Email Activity - Emails have been around for a long time and are a favorite tool for hackers. Hackers use phishing attacks to get into the networks of a business. Increased email activity is a sign of a possible phishing attack. A business may hope that they have taught their employees how to avoid this type of attack, but they also need to take steps to prevent these attacks from reaching the employees. Auditing email records is one way to do this type of cyber security.
Stopping the Threats
Cyber security is similar to insurance. People spend money on insurance with the hope that they never have a need for it. Businesses invest in security for their computer systems and networks with the hopes that a hacker never attempts to get into them. The good news is that hackers are looking for the easiest targets to attack. The businesses that take the time and energy to protect their networks through the use of different threat intelligence services and by learning where to look for threats are the ones that are a target hackers avoid.

What do you get when you combine Big Data technologies….like Pig and Hive? A flying pig? No, you get a “Logical Data Warehouse.” In 2012, Infochimps (now CSC) leveraged its early use of stream processing, NoSQLs, and Hadoop to create a design pattern which combined real-time, ad-hoc, and batch analytics. This concept of combining the best-in-breed Big Data technologies will continue to advance across the industry until the entire legacy (and proprietary) data infrastructure stack will be replaced with a new (and open) one.
While unprecedented technological advances have been made in healthcare in areas such as genomics, digital imaging and Health Information Systems, access to this information has been not been easy for both the healthcare provider and the patient themselves. Regulatory compliance and controls, information lock-in in proprietary Electronic Health Record systems and security concerns have made it difficult to share data across health care providers.

Everyone talks about a cloud-first or mobile-first strategy. It's the trend du jour, and for good reason as these innovative technologies have revolutionized an industry and made savvy companies a lot of money. But consider for a minute what's emerging with the Age of Context and the Internet of Things. Devices, interfaces, everyday objects are becoming endowed with computing smarts. This is creating an unprecedented focus on the Application Programming Interface (API) as developers seek to connect these devices and interfaces to create new supporting services and hybrids. I call this trend the move toward an API-first business model and strategy.
We live in a world that requires us to compete on our differential use of time and information, yet only a fraction of information workers today have access to the analytical capabilities they need to make better decisions. Now, with the advent of a new generation of embedded business intelligence (BI) platforms, cloud developers are disrupting the world of analytics. They are using these new BI platforms to inject more intelligence into the applications business people use every day. As a result, data-driven decision-making is finally on track to become the rule, not the exception.
