According to the IDG 2017 Global State of Information Security Survey, 62 percent of the 10,000 respondents use managed security services for cybersecurity and privacy. This shows that enterprises understand the need for end-to-end security and well-defined policies that align with their business objectives. Of course, this journey must start with creating a plan of action for responding to each type of threat and the specific IT security services needed to do so.
IT services should be chosen to enable a comprehensive response strategy to different threats. Although foundational, this goes beyond patch management, data backup, and full disk encryption. By using policy-based solutions like next-generation firewalls, behavioral firewalls, and other network security devices, enterprises can obtain the desired level of security.
FIREWALLS AND VPNS
Next-generation firewalls can help protect the enterprise from attacks outside the perimeter of the network while VPNs provide security with data transmissions inside and outside those parameters. An integrated firewall/VPN client can automatically enforce security on a more granular level with enterprises’ data transmissions on a remote office/branch office and user level. The many features of VPNs and next-gen firewalls enable administrators to:
- Enforce centrally managed client security policies
- Implement rule-based access control on clients
- Specify different policies for different user groups
Organizations with different types of remote-access VPN users—such as salespeople and IT staff—can tailor desktop security policies to the varying needs of their users via the cloud. Other important services for access to cloud applications include:
- Single sign-on
- Multifactor authentication
- Role-based access controls
- Behavioral firewalls
- Privileged identity management tools
These can all help rapidly and systematically restrict access to users if required and can define security policies by individual, group, or organization. Then there are other IT security services such as endpoint detection and response solutions, network security monitoring, and advanced security analytics. These services work to provide monitoring and analysis of endpoints, traffic, and log analysis of internal machines and security event/incident management and monitoring.
BACKUP AND RECOVERY
Finally, backup and recovery services are a crucial part of end-to-end IT security services. Cloud backup and recovery has become a part of most enterprises where full, differential, or incremental backups are utilized. The choices of public, private, or hybrid cloud backup is dependent on the security needs as well as the TCO parameters that the business has set.
Hybrid cloud backup is the combination of both cloud backup and on-premises or private cloud backup. Hybrid cloud data recovery utilizes VM image backups that are copies of the current VM or a physical server (V2V and P2V, respectively) as part of the backup process. The local storage appliance stores these images in the event of the primary server going down.
This enables server consolidation where a single server can act as a standby for multiple virtual and physical servers. In this case, hosted disaster recovery services can provide high availability to the production server environments as part of their backup infrastructure. Ultimately, the VM images are moved to the cloud provider, which can provide the backup from a choice of strategically placed data centers.
IT SECURITY IN THE DIGITAL AGE
In the digital age, enterprises must prepare for the inevitability of cyberattacks that can compromise the business in monumental ways. The implementation of end-to-end IT security services, along with the policies that govern their use, provide granular and graduated responses that enable businesses to circumvent attacks. The goal is to give them more options and flexibility so that the entire business does not have to come to a grinding halt to keep threats at bay.
