SDNs: Managing Security Across the Virtual Network

Omer Ganot
Product Manager

Software-defined networks (SDNs) offer an agile and scalable network option, yet the lack of visibility presents a huge challenge for the security and network operations teams who need to secure and manage it.

Join Omer Ganot, Product Manager at AlgoSec, for this technical webinar on best practices for managing security across the SDN environment.

Key topics include:

How to securely discover, map and migrate application connectivity to the SDN

Hybrid & multi-cloud Security challenges

Cloud computing provides improved security, agility, and flexibility. However, integrating this new service into legacy IT environments comes with some great concerns. In a recent survey conducted by the Cloud Security Alliance (CSA) and AlgoSec, security, data loss and compliance were identified as the top 3 concerns when moving to the cloud.

Security Management in the Hybrid Cloud

Challenges: Multiple security platforms, multiple clouds and multiple stakeholders

IT and Security staff find it difficult to create and maintain security in the cloud due to:
  • COMPLEXITY OF MULTIPLE LAYERS OF SECURITY CONTROLS –Hybrid networks have multiple security controls, including AWS’s builtin security controls, such as security groups and network ACLs. Cloud assets such as EC2 instances, DBaaS, and serverless functions need protection. Misconfigurations introduce security risks across various assets, including IaaS and PaaS.
  • MULTIPLE PUBLIC CLOUD ACCOUNTS –Enterprises have multiple cloud instances spread across multiple accounts, regions and VPCs. Security professionals need to understand their different accounts, while managing them separately using different account consoles and multiple tools.
  • MULTIPLE STAKEHOLDERS MANAGING CLOUD DEPLOYMENT –In on-premises networks, policies are typically managed by security teams. But in cloud environments such as AWS, multiple stakeholders manage changes to cloud configurations and security rulesusing different orchestration methods, challenging consistency and control, and increasing the risk of misconfigurations.
  • CHANGE PROCESSES SLOW DOWN BUSINESS -Making changes in complex hybrid and heterogeneous enterprise environments is hard. Assessing the risk of changes is difficult, yet misconfigurations can cause outages and disrupt business. Security
