• Fluctuation effects
• Josephson junction
• noise delayed switching
• noise enhanced stability
• metastability

We present the analysis of the mean switching time and its standard deviation of short over-damped Josephson junctions, driven by a direct current and a periodic signal. The effect of noise enhanced stability is investigated. It is shown that fluctuations may both decrease and increase the switching time.
