Recent studies indicate that there has been a dramatic increase in the frequency and extent of attacks on networks, and that security and data privacy are some of the top concerns among IT professionals. As a result, these experts are examining more varied and flexible methods by which they can monitor network security and respond more quickly to threats.
The total monetary cost of this type of cyber crime was estimated to be around $500 billion in 2015, but network attacks can also negatively impact productivity and public perception.
More Threats Call for More Security
The methodology of attacks is becoming increasingly diverse, with around a quarter of them arising from novel methods — making defense more problematic. Such methods as phishing, skimming, and hacking are giving way to newer and more difficult to detect sieges upon networks, although the former are still the attacks of choice according to the Identify Theft Resource Center (ITRC).
In a study done this year by telecom giant Verizon, phishing and point-of-sale (PoS) attacks were shown to be the most widespread and dangerous emerging threats. Research done in 2015 through a joint IBM-Ponemon Institute venture revealed that the average cost of a network data breach increased 8% between 2014 and 2015, reaching $3.79 million total cost per event.
Employing Virtualization for Security
The mass gravitation of business and consumers to the cloud has resulted in more challenges to those whose job it is to secure networks. A study done by Intel Security revealed that less than 35% of IT professionals believe that their managers grasp the security implications of this in a meaningful way.
All of this implies that in the future, relying on dedicated and proprietary hardware will not fit the bill for dynamic IT environments, which is why the migration to virtualized and cloud-based security is at hand.
Nearly all security functions in use today do have cloud-based analogues, including:
- Data loss prevention (DLP)
- Denial of service (DoS) solutions
- Disaster recovery (DR)
- Intrusion detection and prevention (IDS/IPS)
All of these are currently migrating to cloud-based utilities capable of monitoring applications both in data centers and hybrid clouds, rather than being limited to local or WAN networks. As these are virtualized, integration into the cloud will occur, providing even more effective protection.
The Marriage of Security and Virtualization
The trend in the IT security market is to focus on delivering cloud-based security services and exploiting data from both cloud-based and virtual environments in order to police networks and quickly detect irregularities. Additionally, NV and SDN platforms are building in analytics functionality, which will be employed to enhance security. Rollbacks, snapshotting, and micro segmentation are also being used to bolster network security.
