Sept 10 (Reuters) - Microsoft ( MSFT ) will hold a

summit on Tuesday to discuss steps to improve cybersecurity

systems, after a faulty software update from CrowdStrike ( CRWD )

caused a global IT outage in July.

The conference marks the first significant step by Microsoft ( MSFT )

to address the issues that affected nearly 8.5 million Windows

devices on July 19, disrupting operations across industries

ranging from major airlines to banks and healthcare.

The event will be held at Microsoft's ( MSFT ) headquarters in

Redmond, Washington, and will include invited government

representatives.

The July outage raised concerns that many organizations are

not well prepared to implement contingency plans when a single

point of failure such as an IT system, or a piece of software

within it, goes down. Analysts have said the outage also exposed

risks of dependence on a single vendor providing a one-stop shop

for security solutions.

Delta Air Lines ( DAL ) has said it was pursuing legal

claims against CrowdStrike ( CRWD ) and Microsoft ( MSFT ), after the outage

caused mass flight cancellations and cost the carrier at least

$500 million.
