Today’s use of the cloud infrastructure in the enterprise is advancing and adoption is accelerating, but we still hear opposition to it, with claims that making cloud-computing the centerpiece of the firm’s computing dependence is a huge security concern. On the other hand, it is also true that there is a big advantage such as significant cost reduction can be expected by using server consolidation and efficient operation management by using the cloud service. The age-old practice of purchasing server hardware, installing server-based software and maintaining such a setup within the organization is beginning to erode. By understanding the service provider’s security response status, it may be an opportunity to choose an appropriate service and take a step towards the realization of the cloud, convenience to all users.
One of the security worries often hyped by the critics of the cloud is the risk of “information leakage“. Because the scope of brand damage is large and loyal customers’ trust is lost, all measures that can prevent data breach must be done, within a reasonable budget. But in fact, it is said that it is impossible to prevent it completely. Why is that? Malicious users and cybercriminals are starting to attack in new ways, improving their methodology year-over-year. Classic cyber attacks were email-based, like malicious attachments and phishing links, but in recent years there have been techniques such as social engineering attacks that bring about human psychological gaps and the emergence of methods that give the opportunity for cyber attacks while unknown.
In addition, not only PCs but also devices that can access the Internet, such as smartphones and tablets, are handled by firms using a mode known as BYOD (Bring Your Own Device), with it corporate lifestyles are also changing dramatically. In such an environment, it is very difficult to completely protect the information, there is no way for an IT team to keep track devices that are owned by the employees themselves while being used for work. That’s why it is an efficient and very effective way to improve security by “squeezing the entrances into one.“ Being able to narrow down the number of entrances to the Internet from the corporate network inevitably limits security enforcement, which not only significantly reduces risk but also saves time and money.
For example, in a retail chain, multiple packages are collected and managed. For this reason, measures are taken such as installing sufficient security and a door that can not be easily broken. Similarly, in the data center where customer information is gathered from many companies, in addition to robust facilities and strong security equipment, data center specialists and information security technology experts are treating data as the lifeblood of the company’s operations. It should be firmly protected. Intrusion by 3rd parties must be made difficult, if not impossible through clever use of technology such as encryption. In fact, the capability to for systems to notice abnormality is more important than perfect protection. Even if there is unauthorized access, if the entrance is squeezed and if sufficient monitoring is done, it is necessary to quickly identify the cause and to immediately deal with the cause of the intrusion and who is the offender.
In other words, the “cloud” and “data center” where data are collected are always managed and managed with the latest security measures in place and are managed and managed appropriately It is a space protected by a variety of facilities and is considered more secure than proprietary infrastructure. Other points that should be viewed from a security perspective, such as the Virtual LAN (VLAN), which virtually separates the network from other users’ networks, and the multiuser function that limits user access to data by separating user rights. Security attacks and countermeasures are intensifying and changing every day.
